The recent emergence of magnetic van der Waals materials allows for the investigation of current induced magnetization manipulation in two dimensional materials. Uniquely, Fe3GeTe2 has a crystalline structure that allows for the presence of bulk spin-orbit torques (SOTs), that we quantify in a Fe3GeTe2 flake. From the symmetry of the measured torques, we identify the current induced effective fields using harmonic analysis and find dominant bulk SOTs, which arise from the symmetry in the… Expand


Efficient Spin-Orbit Torque Switching of the Semiconducting Van Der Waals Ferromagnet Cr2 Ge2 Te6.
The results presented here show the potential of 2D ferromagnets for low-power memory and logic applications and highlights that current densities required for spin-orbit torque switching of Cr2 Ge2 Te6 are about two orders of magnitude lower than those required for switching nonlayered metallic ferromagnet such as CoFeB.

It is confirmed that an oxide layer (O-FGT) naturally forms on top of exfoliated FGT and that an antiferromagnetic coupling (AFC) exists between F GT and O-F GT layers. Expand
Discovery of intrinsic ferromagnetism in two-dimensional van der Waals crystals
It is concluded that Cr2Ge2Te6 is a nearly ideal two-dimensional Heisenberg ferromagnet and so will be useful for studying fundamental spin behaviours, opening the door to exploring new applications such as ultra-compact spintronics. Expand
Highly Efficient Spin-Orbit Torque and Switching of Layered Ferromagnet Fe3GeTe2.
Heterostructures of FGT/Pt with 5 nm of Pt sputtered onto the atomically flat surface of ∼15-23 nm exfoliated FGT flakes are fabricated, showing that the SOT efficiency is comparable with that of the best heterostructure containing three-dimensional (3D) ferromagnetic metals and much larger than that of heterostructure containing 3D ferrimagnetic insulators.

Current Control of Magnetism in Two-Dimensional Fe_{3}GeTe_{2}.
This work identifies a recently realized system in which the current-induced spin torque is particularly simple and powerful and enables unprecedented control and provides the possibility to study the Berezinski-Kosterlitz-Thouless phase transition in the 2D XY model and its associated critical exponents.

Symmetry and magnitude of spin-orbit torques in ferromagnetic heterostructures.
This work reports on the three-dimensional vector measurement of SOTs in AlOx/Co/Pt and MgO/CoFeB/Ta trilayers using harmonic analysis of the anomalous and planar Hall effects and demonstrates that heavy metal/ferromagnetic layers allow for two different Sots having odd and even behaviour with respect to magnetization reversal.

Gigantic Current Control of Coercive Field and Magnetic Memory Based on Nanometer-Thin Ferromagnetic van der Waals Fe3 GeTe2.
It is reported that, surprisingly, an in-plane current can tune the magnetic state of the nanometer-thin van der Waals ferromagnet Fe3 GeTe2 from a hard magnetic state to a soft magnetic state. Expand
Ferromagnetic Order, Strong Magnetocrystalline Anisotropy, and Magnetocaloric Effect in the Layered Telluride Fe(3-δ)GeTe2.
