Abstract
With more than 300 papers published on the topic, the Condensed Matter group in Leeds is well known for its work on spintronics - a subject defined by the exploitation of the magnetic moment of electrons instead of charge. Recently the group has appointed two new members of staff bringing us expertise in organic spintronics (Cespedes) and nanomagnetism (Moore). Thus we are one of the first groups to develop high frequency equipment for molecular spintronics in order to research eco-friendly microwave devices. We are also exploring ways of switching magnetisation using the strain developed by an electric field - important for future storage applications. Although we have links among all members of the group, this Platform provides an excellent opportunity to take a strategic look at our activity.
Our broad research strategy will concern the general theme of spintronic metamaterials. Metamaterials are artificial in that the functional properties are not a feature of the natural occurring materials that form the building blocks, but emerge through design and engineering of material combinations. The artificial aspect is often introduced through nanostructuring. An early example arises in optics where sub-wavelength features give rise to new properties such as photonic band-gap crystals. Magnetic metamaterials were at the dawn of spintronics - a multilayer composed of alternating magnetic and non-magnetic metals displays giant magnetoresistance. These properties have been exploited to great advantage in computing and communication. We aim to move from common magnetoresistive devices and spin transport physics into microwave nanodevices that manipulate the interactions between electrons with phonons, magnons and other quasiparticles in hybrid structures.
Building on our recognised strengths of thin film growth, characterisation and magnetotransport we are proposing a programme of engineering materials in combinations that yield fruitful emergent properties - spintronic metamaterials. Our group has a broad background that includes the ability to structure materials at the nanoscale so that cooperative behaviour arises, e.g. combining superconductors with skyrmion spin textures, or injecting pure spin currents from magnets into organics. We will apply this capability to questions in areas identified as strategic such as quantum effects for new technology, beyond CMOS electronics, energy efficient electronics and new tools for healthcare.
We shall pursue this in a way that is very different from a traditional responsive-mode research project. We have identified areas that are scientifically and nationally important and where we can make impact in both academic and technological settings. We will not specify exactly which experiments will be performed, only the type of experiment that is possible. We will use the flexibility of platform funding to develop the independence of researchers beyond that achievable in a normal grant. As an example, there is a controversy at present about the role of heat and magnetic proximity effects in spin currents and their possibilities in non-dissipative, low power consumption electronics. With platform funding we can send a researcher to visit the relevant labs and attend the workshops who would then be in a good position to recommend the best course of action. The researcher would lead those experiments with full support for necessary resources - including and encouraging, if appropriate, the contribution of PhD students and other PDRAs. This general approach can be applied across our whole platform programme to any emerging problems in the field. This is career-enhancing because researchers, at this stage of their research, can usually only gain this level of autonomy if they are independent Research Fellows. This background will fast track them for Research Fellowships or good positions in industry or top level institutions looking for individuals with initiative and vision.

Planned Impact
This platform programme encompasses a broad research programme based around the concept of nanomagnetic/spintronic metamaterials. Spintronics has been one of the most commercially successful nanotechnologies, with the giant and tunnel magnetoresistance effects having delivered the vast, yet cheap, data storage capacity of hard disks upon which the internet/social media revolution has been based. Low power solid state magnetic random access memories that are based on another spintronic effect, the spin transfer torque, are now coming close to market. Future developments will enable nanomagnetic/spintronics information processing, perhaps exploiting unconventional neuromorphic or quantum architectures.
The importance of advanced functional materials and their potential impact is explicitly recognized in their inclusion in the "Great Eight Technologies" identified by BIS, recently augmented by Quantum Technologies. This Platform grant is aimed at directly addressing this challenge, developing new magnetic and spintronic metamaterials that exhibit novel functional properties. A particular area of impact is energy efficient computing, another of the great eight technologies. The central idea is that the materials combinations and nanostructuring forming the metamaterial give rise to emergent properties that are not exhibited by the component parts in isolation: the view encapsulated by Nobel laureate Herbert Kroemer when he coined the famous phrase that "the interface is the device". Our results will have impact in the ITC sector in particular, where spintronics has already enabled the huge amounts of extremely cheap data storage needed to provide social media, such as Facebook, Twitter, and Youtube, free to users. Nevertheless, the reality is that the world's server farms are consuming 30 billion watts of power. Furthermore, only about 10% of this energy is actually used for computation. The remainder is used to keep servers available should an urgent demand be requested, and to run cooling systems to dissipate this enormous amount of waste heat. As long ago as 2008, it was pointed out that the carbon footprint of the internet exceeds that of commercial air travel. As the rates of data production and consumption increase, this is clearly not sustainable. As the data volumes are unlikely to reduce, we need to search for new materials that will permit new devices and architectures to greatly more efficient use of energy, and to scavenge waste heat and turn it back into useful power.
The other principal means of realising impact will be the provision of highly skilled people to the wider world, achieved through the superb training and developmental environment in the Condensed Matter Physics group. Since the academic job market is very limited, it is clear that most of our early stage researchers will, in the fullness of time, have to pursue the next stage of their career in another kind of organisation. Our Platform researchers will develop faster than they otherwise might in a conventional project-based setting, since they will have freedom to propose and pursue their own research goals and thus participate in strategy-setting for the group, undertake secondments to leading international and industrial research partners, and have exceptional opportunities for developing management and leadership abilities through mentoring and helping supervise under- and postgraduate student researchers. Moreover, we have a state-of-the-art laboratory with advanced nanofabrication, synthesis, characterisation, measurement, and simulation capabilities. Acquiring these technical skills is another asset for our researchers as future employees, as demonstrated by our track record of placing graduates the group in leading institutions in academia, national laboratories, and industry.

Description | (i) Weak antilocalisation measurements in moderately disordered InAs/GaBs coupled wells allow measurements of the strength of the spin-orbit interaction, and how it is affected by things like temperature and gate voltage, through the spin-orbit length (ii) that such a structure into which a thin AlSb barrier has been introduced shows an electron-like conduction channel as well as a hybridised one with a much higher effective mass. (iii) The decrease in the spin diffusion length in pure spin current conduits has been quantitatively explained as due to Kondo scattering from magnetic impurities (iv) Three terminal devices using pure spin currents have demonstrated Kirrchoff's laws apply. (v) Tuning domain wall energy with strain, by balancing anisotropy and exchange energies. (vi) The characteristics and commonality of the emergent magnetism effect for future energy and computing metamaterials with minimum ecological impact. (vii) We find for the first time the effects of pure spin currents on the optical properties of molecular layers, which has potential applications in optoelectronic and low dissipation devices. (viii) Effect of substrate temperature on the magnetic properties of epitaxial sputter-grown Co/Pt, (ix) Discovered the downturn in magnetisation in thin film YIG is due to an extra magnetic layer at the interface between GGG and YIG that orders antiparallel to YIG at low temperatures. (x) we have gained further understanding of heat transport in nanostructures and how it affects spin transport. (xi) We have increased the spin polarisation and subsequent spin injection into lateral spin valves - this could be important for furtre devices. (xii) Measurement of Co layer thickness dependence of magnetization, perpendicular anisotropy, exchange stiffness and interfacial DMI in Pt/Co/Ir trilayers, highlighting changes in domain wall creep parameters with in-plane field that theoretical models currently neglect; (xIII) Characterisation of magnetic domains and measurement of interfacial DMI in Pt/Co/IrMn and Pt/Co/FeMn trilayers, showing that while the domain morphology is sensitive to the spin order in the antiferromagnetic layer, the DMI is not. (xiv) A complete description of the thermal behaviour of lateral spin valves has been published resulting in the discovery that at low temperatures the phonon wavelength in the substrate exceeds the sample dimensions resulting in ballistic phonon transport. |

Title | Dataset associated with 'Pinning and hysteresis in the field dependent diameter evolution of skyrmions in Pt/Co/Ir superlattice stacks' |
Description | We have imaged Néel skyrmion bubbles in perpendicularly magnetised polycrystalline multilayers patterned into 1 µm diameter dots, using scanning transmission x-ray microscopy. The skyrmion bubbles can be nucleated by the application of an external magnetic field and are stable at zero field with a diameter of 260 nm. Applying an out of plane field that opposes the magnetisation of the skyrmion bubble core moment applies pressure to the bubble and gradually compresses it to a diameter of approximately 100 nm. On removing the field the skyrmion bubble returns to its original diameter via a hysteretic pathway where most of the expansion occurs in a single abrupt step. This contradicts analytical models of homogeneous materials in which the skyrmion compression and expansion are reversible. Micromagnetic simulations incorporating disorder can explain this behaviour using an effective thickness modulation between 10 nm grain |

Title | Strain and domain wall creep in Pt-Co-Ir thin films |
Description | We study the energy and creep velocity of magnetic domain walls in perpendicularly magnetised Pt/Co/Ir thin films under strain. We find that the enhancement of domain wall creep velocity under strain from piezoelectric transducers is largest in films with the thinnest Co layers (0.56 nm), in which the strain causes the smallest relative change in perpendicular magnetic anisotropy and the largest relative change in domain wall creep velocity. We show how domain wall energy is predictive of the sensitivity of domain wall creep velocity to changes in strain, and thus provide a route to designing magnetic thin film systems for optimum strain control. |
