Fig. 1: Orbital torque in van der Waals ferromagnet.
From: Orbital torque switching of room temperature two-dimensional van der Waals ferromagnet Fe3GaTe2
a Schematic of the Fe3GaTe2/Ti orbital torque heterostructure, in which the Ti orbital Hall material converts the charge current ( JC) into the orbital current ( JL), then the orbital current (JL) flows into the 2D-vdW FM Fe3GaTe2 layer and is converted into the spin current (JS) due to the spin-orbit coupling of the Fe3GaTe2 layer. b The calculated orbital Hall conductivity (blue line) and spin Hall conductivity (red line) of the Ti orbital Hall material. c The microstructure of the Fe3GaTe2/Ti heterostructure measured by the atomic-resolution scanning transmission electron microscopy (STEM).
