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 …

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 …

It has been suggested that certain antiferromagnetic topological insulators contain axion
quasiparticles (AQs), and that such materials could be used to detect axion dark matter …

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 …

Magnetic anisotropy phenomena in bimetallic antiferromagnets Mn 2 Au and MnIr are
studied by first-principles density-functional theory calculations. We find strong and lattice …

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 …

We derive a phenomenological theory of current-induced staggered magnetization
dynamics in antiferromagnets. The theory captures the reactive and dissipative current …

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 …

Antiferromagnets can be used to store and manipulate spin information, but the coupled
dynamics of the staggered field and the magnetization are very complex. We present a …

Magnetic whirls in chiral magnets, so-called skyrmions, can be manipulated by ultrasmall
current densities. Here we study both analytically and numerically the interactions of a single …
