Current-induced torques in textured Rashba ferromagnets

Spin-orbit torques in two-dimensional Rashba ferromagnets

Spin-motive forces and current-induced torques in ferromagnets

In metallic ferromagnets, the spin-transfer torque and spin-motive force are known to exhibit a reciprocal relationship. Recent experiments on ferromagnets with strong spin-orbit coupling have revealed a rich complexity in the interaction between itinerant charge carriers and magnetization, but a full understanding of this coupled dynamics is lacking. Here, we develop a general phenomenology of...

Laser-induced torques in metallic ferromagnets

We study laser-induced torques in bcc Fe, hcp Co, and L10 FePt based on first-principles electronic structure calculations and the Keldysh nonequilibrium formalism. We find that the torques have two contributions, one from the inverse Faraday effect (IFE) and one from the optical spin-transfer torque (OSTT). Depending on the ferromagnet at hand and on the quasiparticle broadening the two contri...

Theory of light-induced effective magnetic field in Rashba ferromagnets

Current-induced torques in magnetic materials.

The magnetization of a magnetic material can be reversed by using electric currents that transport spin angular momentum. In the reciprocal process a changing magnetization orientation produces currents that transport spin angular momentum. Understanding how these processes occur reveals the intricate connection between magnetization and spin transport, and can transform technologies that gener...
