Over the past two decades, the research of (Ga, Mn) As has led to a deeper understanding
of relativistic spin-dependent phenomena in magnetic systems. It has also led to discoveries …

Magnetization switching by current-induced spin–orbit torques is of great interest due to its
potential applications in ultralow-power memory and logic devices. The switching of …

Electrons in two-dimensional crystals with a honeycomb lattice structure possess a valley
degree of freedom (DOF) in addition to charge and spin. These systems are predicted to …

We present a theory of the anomalous Hall effect (AHE) in a doped Weyl semimetal, or Weyl
metal, including both intrinsic and extrinsic (impurity scattering) contributions. We …

Magnetization switching at the interface between ferromagnetic and paramagnetic metals,
controlled by current-induced torques, could be exploited in magnetic memory technologies …

We provide a precise microscopic definition of the recently observed inverse Edelstein effect
in which a nonequilibrium spin accumulation in the plane of a two-dimensional (interfacial) …

Spin torque from spin current applied to a nanoscale region of a ferromagnet can act as
negative magnetic damping and thereby excite self-oscillations of its magnetization. In …

Bismuth Selenide (Bi 2 Se 3) is a topological insulator exhibiting helical spin polarization
and strong spin-orbit coupling. The spin-orbit coupling links the charge current to spin …

Superfluid spin transport—dissipationless transport of spin—is theoretically studied in a
ferromagnetic insulator with easy-plane anisotropy. We consider an open geometry where …

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 …
