  We study the spin orbit torque arising from an intrinsic linear Dresselhaus
spin-orbit coupling in a single layer III-V diluted magnetic semiconductor. We
investigate the transport properties and spin torque using the linear response
theory and we report here : (1) a strong correlation exists between the angular
dependence of the torque and the anisotropy of the Fermi surface; (2) the spin
orbit torque depends nonlinearly on the exchange coupling. Our findings suggest
the possibility to tailor the spin orbit torque magnitude and angular
dependence by structural design.
