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 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 …

Spin manipulation using electric currents is one of the most promising directions in the field
of spintronics. We used neutron scattering to observe the influence of an electric current on …

Recent small angle neutron scattering suggests that the spin structure in the A phase of
MnSi is a so-called triple-Q state, ie, a superposition of three helices under 120 degrees …

Geometry, both in momentum and in real space, plays an important role in the electronic
dynamics of condensed matter systems. Among them, the Berry phase associated with …

Spin-transfer torques can switch magnetizations via a current passing through a magnetic
tunnel junction, an effect that is being pursued as the switching mechanism in spin-transfer …

A review of geometrically confined 180 head-to-head domain walls is presented. The spin
structures of head-to-head domain walls are systematically determined by direct imaging …

Berry phases occur when a system adiabatically evolves along a closed curve in parameter
space. This tutorial-like article focuses on Berry phases accumulated in real space. In …

We report detailed low-temperature magnetotransport and magnetization measurements in
MnSi under pressures up to∼ 12 kbar. Tracking the role of sample quality, pressure …

Spin-transfer torque (STT) effects on DW motion in rare earth-transition metal (RE-TM)
ferrimagnets are investigated both theoretically and experimentally across the angular …
