Abstract

Traditional electronics exploits the charge degree of freedom of carriers in metals, semiconductors, and superconductors to construct a broad range of omnipresent devices, with applications ranging from computation and transmission of data to sensing of biological material. In the past two decades, we have begun to take advantage of the magnetic degree of freedom that is also inherently found in these carriers. Often referred to as spintronics , technology based on the interplay between charge and spin offers revolutionary new functionality including non-volatility in data storage, higher sensitivity in sensors, and improved performance in the consumption of energy. The first generation of spintronic devices based on magnetic and non-magnetic metal heterostructures has already had significant commercial impact with the introduction of GMR-based read heads, and promises continued success with the development of new MRAM devices.Recent advances in scanning probe microscopy have enabled us to explore these systems at the single atom scale. The goal of this proposal is to gain an understanding of the electronic, magnetic, and structural properties of spintronic systems at the molecular level, and use this to develop new types of devices. This timely marriage of the nascent discipline of spintronics with the power and flexibility of organic chemical synthesis would enable a step-change reduction in device dimensions and extend functionality to unconventional (e.g. flexible) structural and low-cost environments.

Description - Developed molecular materials which displays magnetic couplings up to 100K. This is one order of magnitude higher than previous results on similar materials.

- Developed films of materials whose magnetic properties can be switched using light.

- Correlate observations on the molecular level (using scanning tunnelling microscopy) with those on flexible continuous films.
Exploitation Route Develop strategies to further increase magnetic strength in moelcular materials. Use molecular materials for spintronic applications.

Policy Influence Type Membership of a guideline committee
Impact MatSEEC is an ESF Temporary Expert Committee in the remit of and associated with the ESF Standing Committee for Physical and Engineering Sciences (PEN (formerly PESC)) with a task related term of 5 years starting on the date of its inauguration meeting. The mission shall include delivering foresight reports and scientific advice to PEN (formerly PESC) and ESF on issues related to Materials Science and Engineering and matters of concern to the related scientific communities, as well as to European National Agencies and Ministries, institutions of the European Commission, and the European Strategic Forum on Research Infrastructures (ESFRI) upon request. The mission also included tasks related to peer-review and assessment of scientific research proposals. Further the Committee provided foresight surveys and scientific advice to ESF member organisations and European organisations. The Committee prepared strategic policy documents.
