  • Interfacial spin-orbit torque allows electrical manipulation of magnetization, but this has been shown mostly in polycrystalline metal bilayers. Here the authors show robust spin-orbit torque in single crystalline Fe/GaAs interface at room temperature, observing conversion between spin and charge current.

  • Current-induced spin–orbit magnetic fields at an Fe/GaAs (001) interface can be controlled with an electric field in the Schottky barrier, an effect that could be used to develop low-power spin–orbit torque devices.

  • Broken symmetry at material interfaces allows for novel spintronic functionality via emergent spin–orbit effects. Here, Hupfauer et al. follow the interface-to-bulk transition of ultra-thin epitaxial iron films on gallium arsenide via anisotropic magnetoresistance measurements and first-principle calculations.

  • The nature of the dominant pairing mechanism in some two-dimensional transition metal dichalcogenides is still debated. Here, the authors predict that the Kohn-Luttinger mechanism induces chiral p-wave superconductivity in monolayer NbSe2.

  • The Gilbert damping constant, a fundamental parameter to describe magnetization dynamics, is an isotropic scalar for most magnetic materials. Now, at a metal/semiconductor interface, the emergence of anisotropic magnetic damping has been observed.

  • Graphite consists of individual layers of graphene stacked vertically and held together via van der Waals forces. Here, Markus et al studied the spin relaxation in graphite, and find a giant anisotropy between spin-relaxation time in graphite, with magnetic field aligned perpendicular to the graphene planes exhibiting a factor of 10 longer spin-relaxation time.

  • Here, the authors report on the large twist-angle susceptibility of excitons involving upper conduction bands in transition metal dichalcogenide bilayers. These high-lying excitons couple with band-edge excitons, and give rise to nonlinear quantum-optical processes that become tuneable by twisting.

  • A strong lightwave in a monolayer of tungsten diselenide drives changes in the valley pseudospin, making valley pseudospin an information carrier that is switchable faster than a single light cycle.
