The influence of spin-diffusion effects on current driven domain-wall motion

Micromagnetic studies of current driven domain-wall motion nowadays usually employ a local spin-transfer torque model by Zhang and Li. In this model the right-hand side of the Landau-Lifshitz-Gilbert equation is extended by two torque terms referred to as adiabatic and nonadiabatic spin torque . The prefactor of the nonadiabatic term β describes the degree… CONTINUE READING
