Growth, strain, and spin-orbit torques in epitaxial Ni-Mn-Sb films sputtered on GaAs
Growth, strain, and spin-orbit torques in epitaxial Ni-Mn-Sb films sputtered on GaAs
We report current-induced spin torques in epitaxial NiMnSb films on a commercially available epiready GaAs substrate. The NiMnSb was grown by cosputtering from three targets using optimized parameters. The films were processed into microscale bars to perform current-induced spin-torque measurements. Magnetic dynamics were excited by microwave currents, and electric voltages …
