Abstract
The magnetization dynamics of a ferromagnet subjected to an electrical current are given by an extension of the Landau-Lifshitz-Gilbert equation that contains two additional terms, the adiabatic and non-adiabatic spin-transfer torques. First-principles calculations of the non-adiabatic spin-transfer torque parameter beta for bcc iron and fcc nickel show that beta is related to and on the same order as alpha, the damping constant, but is distinct from it.Citation
