Abstract
Recent advances have shown that efficient electrical control of antiferromagnetic (AF) order is possible. The reorientation of the AF Neel vector is predicted to happen extremely quickly and also to have an affect on the band structure of certain antiferromagnets. This project will explore the stability, speed and affect on band structure of electrical switching in various AF compounds.

| Description | A greater understanding of how antiferromagnets work has been achieved. In particular, the mechanism behind electrical switching of antiferromagnets, a fundamental part of developing spintronics devices, has been looked at in more detail. Temperature, field and current density dependent studies have been conducted, which have been combined with different methods of measuring the magnetic state (for example, photoemission electron microscopy) to give a clear picture of what happens to the magnetic order during/after applying electrical pulses. |
| Exploitation Route | Whilst a lot of work has been to done to prove the magnetic origin of the switching effects we measure in antiferromagnets, non-magnetic signals are having some influence as well. Future work should focus on untangling magnetic and non-magnetic effects. This can be done by using different measurement techniques, which rely on the magnetic order, to eliminate the effects of non-magnetic signals. |
