Novel methods and new materials for current-induced magnetization dynamics

Over the last few years, a great deal of research in the field of spintronics has been devoted to manipulation of magnetization using electric currents rather than magnetic fields, with the longterm goal of advancing magnetic-memory technology. The underlying physical mechanism, dubbed spin transfer, is usually understood in terms of conservation of spin angular momentum. In this talk I will discuss new directions for current-driven magnetization dynamics that go beyond this "state-of-the-art". These include current-induced torques in antiferromagnets, spiral magnets, and in systems with strong spin-orbit coupling.
