Charge-to-spin conversion is a key theme of spintronics and its realization in topological materials is highly desired. Here, Liu et al. report spatial imaging of current-induced spin accumulation at the edges of Bi2Se3 and BiSbTeSe2 topological insu

Abstract The Weyl semimetal WTe2 and MoTe2 show great potential in generating large spin currents since they possess topologically protected spin‐polarized states and can carry a very large current density. In addition, the intrinsic non‐centrosy

All-optical re-switching has been investigated in the half-metallic Heusler ferrimagnet Mn2Ru0.9Ga, where Mn atoms occupy two inequivalent sites in the XA-type structure. The effect of a second 200 fs 800 nm pump pulse that follows a first pulse, whe

Repeated uniform switching of the magnetization of thin films of ferrimagnetic amorphous Gdx(FeCo)1−x in response to single fast laser pulses is well established. Here, we report unusual toggle switching in thin films of sperimagnetic amorphous Dyx

Energy-efficient control of magnetization without the help of a magnetic field is a key goal of spintronics. Purely heat-induced single-pulse all-optical toggle switching has been demonstrated, but so far only in Gd-based amorphous ferrimagnet films.

The authors experimentally resolve the pulse- and temperature-dependent limits of single-shot alloptical magnetic switching in the compensated three dimensional ferrimagnet, revealing that the process is driven by exchange relaxation.

Here we study both static and time-resolved dynamic magnetic properties of the compensated ferrimagnet from room temperature down to 10K, thus crossing the magnetic compensation temperature $T_{M}$. The behaviour is analysed with a model of a simple

Charge-to-spin conversion in various materials is the key for the fundamental understanding of spin-orbitronics and efficient magnetization manipulation. Here we report the direct spatial imaging of current-induced spin accumulation at the channel ed

Magnetic proximity effects can lead to novel phenomena in the transport properties of topological insulators. In this study, we demonstrate a characteristic fourfold symmetry in the angular dependence of magnetoresistance in the topological insulator
