Perpendicularly magnetized thin films grown on semiconductors are essential for vertical spin sources of spin-based semiconductor devices, such as spin transistors and spin-LEDs. Towards realization of these spintronic devices, electrical manipulation of magnetization direction with high efficiency is requisite. In this study, we investigated a spin-orbit torque (SOT) induced magnetization switching of MnGa/Fe bilayer grown on GaAs. We observed clear perpendicular magnetic anisotropy of the bilayer and clear SOT switching under in-plane magnetic field.
