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 along the bars were measured to analyze the symmetry of the current-induced torques. We found that the extracted symmetry of the spin torques matches those expected from spin-orbit interaction in a tetragonally distorted half-Heusler crystal. Both fieldlike and dampinglike torques are observed in all the samples characterized, and the efficiency of the current-induced torques is comparable to that of ferromagnetic metal/heavy-metal bilayers.}, url = {https://doi.org/10.1103/PhysRevMaterials.5.014413}, author = {Zhao, N and Sud, A and Sukegawa, H and Komori, S and Rogdakis, K and Yamanoi, K and Patchett, J and Robinson, JWA and Ciccarelli, C and Kurebayashi, H} }
