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 …

This review describes in detail the essential techniques used in microscopic theories on
spintronics. We have investigated the domain wall dynamics induced by an electric current …

We study the collective dynamics of the Skyrmion crystal in thin films of ferromagnetic metals
resulting from the nontrivial Skyrmion topology. It is shown that the current-driven motion of …

When a ferromagnet is deposited on the surface of a topological insulator the topologically
protected surface state develops a gap and becomes a two-dimensional quantum Hall …

As nanomagnetic devices scale to smaller sizes, spin-orbit coupling due to the broken
structural inversion symmetry at interfaces becomes increasingly important. Here, we study …

The manipulation of a magnetic domain wall (DW) by a spin polarized current in
ferromagnetic nanowires has attracted tremendous interest during the last years due to …

Magnon drag is shown to dominate the thermopower of elemental Fe from 2 to 80 K and of
elemental Co from 150 to 600 K; it is also shown to contribute to the thermopower of …

We investigate theoretically the dynamics of magnetization coupled to the surface Dirac
fermions of a three-dimensional topological insulator by deriving the Landau-Lifshitz-Gilbert …

Current-induced magnetic domain wall motion, induced by transfer of spin transfer effect due
to exchange interaction, is expected to be useful for next generation high-density storages …

The aim of this paper is to present a comprehensive theory of spintronics phenomena based
on the concept of effective gauge field, the spin gauge field. An effective gauge field …
