摘要

Abstract

The recent emergence of magnetic van der Waals materials allows for the investigation of current-induced magnetisation manipulation in two-dimensional materials. Uniquely

GeTe

has a crystalline structure that allows for the presence of

bulk

spin–orbit torques (SOTs) that we quantify in a Fe

GeTe

flake. From the symmetry of the measured torques

we identify current induced effective fields using harmonic analysis and find dominant

bulk

SOTs arising from the symmetry in the crystal structure. Our results show that Fe

GeTe

can exhibit

bulk

SOTs in addition to the conventional interfacial SOTs enabling magnetisation manipulation even in thick flakes without the need for complex multilayer engineering.
