Description | We are worked on 3 types of advanced magnetic material to combine with semiconductor materials. Structures including our materials will enable new types of efficient spin-electronic devices to be made. We discovered a combination of materials which has outstanding properties for supporting semiconductor spintronics and in collaboration with a group in Japan demonstrated an efficient spintronic device. |
Exploitation Route | We have worked with Toshiba (in Cambridge) to make electronic devices with our advanced materials which could provide low-power, efficient data storage and processing for next-generation computer devices. |
Sectors | Digital/Communication/Information Technologies (including Software) Electronics Energy Manufacturing including Industrial Biotechology |
