| PI Contribution | Project supported as part of the network's 2024 call for pump priming. Applicants: Dr. Daniel Bromley & Dr. Alex Vanstone (Imperial College London) Host: Prof. Takeshi Seki (Tohoku University, Japan) Project description: This project will advance recent work at Imperial College from DB & AV on developing new all- optical magnetic switching (AOMS) technologies which work in simple ferromagnetic materials (NiFe) and using low power continuous-wave lasers (2 mW) [1]. In discussions with the magnetic storage industry, the new technology is deemed of high interest, but the key missing piece is the ability to function with out-of-plane nanomagnets, eg. CoPt. TS is an expert in fabricating and characterising out-of-plane nanomagnets, and this project will combine UK AOMS expertise with Japanese materials & characterisation knowledge & facilities. Large industry players (inc. Seagate) have indicated they are highly-interested in exploring IP licensing if we are able to demonstrate our technology in out-of-plane magnets. Further to this, DB & AV have recently worked on developing neuromorphic computing technologies which utilise spin-waves for magnetic readout [2,3]. Currently, these work using 'flip-chip' broadband FMR which relies on bulky waveguides and electromagnets, unsuitable for device integration. TS is an expert in 'spin torque FMR' (ST-FMR) which allows miniaturisation of spin-wave readout and reduction in RF power by combining heavy metal and ferromagnetic layers for efficient spin-pumping, increasing signal-to-noise and decreasing readout time. TS has also developed unique schemes for using spin-wave excitation to lower the energy- barriers for nanomagnetic switching [4]. In addition to combining Tohoku's expertise at out-of- plane nanomagnet fabrication (CoPt) with efficient, miniature ST-FMR readout, this project will explore a tantalising new approach of using low-power spin-wave excitation to reduce the threshold laser power required for optical switching, with potential to further reduce the laser size and energy needed for our novel AOMS technology. The project has three tiers of goals with corresponding risk/reward: 1. Fabrication & characterisation of CoPt out-of-plane nanoarrays suitable for AOMS. (low risk) 2. Integration of AOMS-compatible CoPt nanoarrays with ST-FMR readout layers (heavy metal Pt/W/Ta and/or ferromagnets NiFe/CoFeB) (low/medium risk) 3. Demonstration of AOMS threshold laser power reduction via ST-FMR spin wave excitation of magnetic nanoarrays (high risk) Goals 1 & 2 have been discussed thoroughly with TS for feasibility, reliability and achievability within the proposed project timescale. TS is confident these are possible with high-likelihood of success, and pre-existing materials and fabrication recipes are in place. TS has agreed that an experienced PDRA Dr. Varun Kushwaha will help us for the duration of our stay to accelerate our research programme. Goal 3 is untested new physics with potentially huge reward. Our existing modelling/simulation results and ultrafast pump-probe experiments point to optical-excitation of 'hot' magnons in nanomagnets as potentially key to our reversal mechanism. The proposed approach uses ST- FMR to excite magnons/spin waves in our nanostructures potentially reducing the additional magnon excitation required by the laser to drive all-optical magnetization switching, thereby lowering the optical threshold power. This could further enhance the technological benefits of the scheme and enable the exploration of new magneto-plasmonic physics. If this behaviour is not found, the completion of goals 1 & 2 alone represents excellent pump-priming value for money. [1] - Stenning, Kilian D., et al.

Nature communications (2013) The advancing field of neuromorphic and in-memory computing stands as a critical frontier in computing, especially with the cessation of Moore's Law and the industry's shift towards specialised chips tailored for tasks like machine learning. Conventional von-Nuemann architectures prove inefficient for AI computation due to the separation of memory and processing costing both speed and energy. Addressing this need is paramount for both societal advancement and market emergence. Our research offers a solution: a cost-effective architecture designed for neuromorphic computing and AI, employing optically controlled nanomagnets. Unlike competing technologies reliant on expensive high-power lasers and toxic magnetic materials, our approach utilises low-power continuous wave lasers (2 mW, similar to a laser pointer or DVD player) to accurately write nanomagnetic states, highly-attractive for physical neural network development. This innovative technology circumvents the challenge of writing information into nanomagnetic arrays without disturbing neighboring elements, offering high input dimensionality and combined magnetic storage & processing, aka 'memcomputing'. While optical methods handle data input, we aim for our scheme to be integrated with ST-FMR technology for GHz spin-wave data readout through a single electrical contact, avoiding the complex fabrication issues of crossbar-style full electrical address and presenting a promising hardware solution for future computing needs. TS at Tohoku University offers a unique capability to afford us the systems and expertise essential to realising the latter ST-FMR part of our technology and migrate our nanomagnetic arrays to out-of-plane anisotropy with far higher technological benefits. Given the success of reading magnetic states via conventional FMR [5], ST-FMR presents itself as a prime candidate to help usher in novel and highly improved neuromorphic technological capabilities which are compatible with commercialisation. Some of our recent research has highlighted the critical role of Py layer growth conditions in achieving successful all-optical magnetic switching rates. Leveraging the growth equipment at Tohoku University promises invaluable insights into this challenge. Additionally, a notable study has demonstrated ultra-fast, single-pulse AOMS in out-of-plane magnetic thin films [6], specifically those containing CoPt, materials in which TS possesses significant expertise. Exploring the miniaturisation of these films into nanomagnet arrays presents a promising avenue for electrically reading optically manipulated systems. However, the lack of an ST-FMR-friendly sublattice and measurement system severely impedes our progress in realising an optically written, low-power system that can be electrically read. Overcoming this hurdle is crucial for advancing both the development of AOMS-neuromorphic technology and its commercialisation potential. This project stands to substantially enhance the technological benefit and scientific progress of two promising & active research strands - novel low-power AOMS and opto-magnetic neuromorphic computing. We are excited to carry out this research programme, and the strong support of our host TS at Tohoku & secondment of TS's PDRA substantially decreases project risk. [5] - Vanstone, Alex, et al.

| Collaborator Contribution | Host supporting statement: This research proposal by DB and AV involves new ideas to overcome the technological issues to develop cost-effective architecture designed for neuromorphic computing and AI, which will be achieved by employing optically controlled nanomagnets. The research plan and the experimental details are carefully considered, and its significance and novelty are obvious. Particularly, the research direction of AOMS threshold laser power reduction via ST-FMR of magnetic nanoarrays is very exciting and it will become a big technological breakthrough if their experiment is successful. I am happy to collaborate with DB and AV, and will strongly support their experiment in Tohoku. They can freely access our equipment of sputtering systems, electron beam lithography, Ar ion milling, rf-compatible probe station with the rf signal generator and so on. Those will allow DB and AV to prepare several kinds of thin films such as CoPt, Pt, W, Ta, NiFe, CoFeB, and to make well-defined nanomagnetic arrays, and to characterise the ST-FMR properties. In addition, DB and AV can use consumables for doing the above experiments. I will cooperate with them so that their experiments will be successful and their goals will be achieved. This collaborative work is not only to build academic network and partners between UK and Japan, but also to open a new research place in which nanotechnology scientists and material scientists jointly work cost-effective architecture designed for neuromorphic computing and AI. |

| PI Contribution | Project funded through the network's 2024 pumnp priming call. Applicant: Dr. Freya Johnson (University of Cambridge) Host: Prof. Shunsuke Fukami (Tohoku University , Japan) Project description: Ultra-fast green computing using antiferromagnets Novel non-collinear antiferromagnets (AFMs) with spontaneous time-reversal symmetry breaking, non-trivial band topology, and unconventional transport properties have recently received immense research interest due to their rich physics and enormous promise in 'beyond von Neumann' computing. With the potential for terahertz operating frequencies, reduced thermal losses and enhanced on-chip packing density, bringing these materials to application now requires an understanding of how to manipulate the AFM domain structure in an efficient manner. [1] Recent research by Tohoku University (Fukami Laboratory) has revealed a unique handedness anomaly in the non-collinear AFM Mn3Sn, demonstrating a distinct switching phenomenon using spin-orbit torque. [2] While in the related material family of manganese antiperovskites Mn3AN (A = Ni, Cu, Sn, Ga), experimental and theoretical works have suggested orders-of-magnitude reduction in the switching current is achievable by modifying the magnetic anisotropy, which can be achieved through strain and chemical doping. [3,4] Increasing the efficiency of this process, and understanding the ultra-fast dynamics, are clear next steps towards commercial devices. To address this, I will begin a new collaboration with Prof. Fukami, developing thin film bilayer devices of non-collinear AFMs and heavy metals. Therefore, I propose the following work package (WP): WP - Rotating Chiral Spins Objectives: Measure the magnetic anisotropy in functional devices, perform nano-scale imaging of the domains and investigate ultra-fast charge-to-spin conversion. T1 - Growth, Characterization and Fabrication: Growth of Mn3NiN films capped with AlN in-situ and structural characterization will be performed at the Henry Royce Institute (Imperial College London). (2 weeks) These films will be sent to Tohoku University where the cap will be removed and Pt deposited, also in-situ. Hall bar devices will be fabricated using photolithography. (8 weeks) T2 - Harmonic Hall measurement: I will travel to Tohoku University and measure the anisotropy using the harmonic Hall technique and analyze the data with their support. (5 weeks) I will return to Cambridge and perform THz spectroscopy and scanning diamond nitrogen vacancy measurements. (8 weeks) This task will be supported by theoretical support at the Czech Academy of Sciences who will help interpret the optical response. Deliverables: (D1) Visit to Tohoku University. (D2) Presentation at Royce technical seminar to disseminate new techniques (D3) 12M Publication identifying the spin-orbit torque switching mechanism in Mn3NiN, with an assessment of the most practical and energy-efficient methods of manipulating the state.

| Collaborator Contribution | Host supporting statement: It is with great enthusiasm that I extend my full support to Dr. Freya Johnson's application, who will be visiting our laboratory at Tohoku University for this collaboration. As the head of a leading research group in the field of non-volatile spintronic devices, I am thrilled at the prospect of hosting such a promising researcher with a shared interest in novel forms of fast and energy-efficient computing. Freya's expertise and experience in non-collinear antiferromagnetic materials aligns perfectly with our current projects and is particularly complementary to our recent work on spin-orbit torque-induced magnetization switching. I am confident that Freya's contributions will be invaluable and that our collaborative efforts will lead to significant advancements, including publications, and will foster an environment for future collaborations with Freya and Chiara. In advance of Freya's visit to our laboratory, we will support this project by preparing the required samples using our advanced deposition equipment and cleanroom facilities for device fabrication. Once she has arrived, we will provide full access to our facilities at the Research Institute of Electrical Communication, in particular our magentotransport measurement system, with associated technical support. Moreover, we will supply the necessary consumables for experimental work, ensuring that Freya has all the resources required to conduct research effectively. I am looking forward to a fruitful collaboration and am excited to see the outcomes of our joint efforts. |

| Results and Impact | This talk was given as a n invited talk at the "EPSRC International Network for Spintronics Kick-Off Meeting: From Material Development to Novel Energy Efficient Technologies" on 9 June 2021. The symposium was held online using Zoom for the first time due to the coronavirus pandemic and travel restriction currently imposed. This has both advantages and disadvantages on the organisation of the symposium. As the advantages, we successfully attracted over 230 participants from 27 countries and encouraged exciting discussion. On the other hand, the online format limited to ask questions directly to presenters unfortunately, which was partially compensated by the networking time allocated at the end of sessions each day. |
