  The recent discovery of ferromagnetism in two-dimensional (2D) van der Waals
(vdW) materials holds promises for novel spintronic devices with exceptional
performances. However, in order to utilize 2D vdW magnets for building
spintronic nanodevices such as magnetic memories, key challenges remain in
terms of effectively switching the magnetization from one state to the other
electrically. Here, we devise a bilayer structure of Fe3GeTe2/Pt, in which the
magnetization of few-layered Fe3GeTe2 can be effectively switched by the
spin-orbit torques (SOTs) originated from the current flowing in the Pt layer.
The effective magnetic fields corresponding to the SOTs are further
quantitatively characterized using harmonic measurements. Our demonstration of
the SOT-driven magnetization switching in a 2D vdW magnet could pave the way
for implementing low-dimensional materials in the next-generation spintronic
applications.
