Domain wall motion in a diffusive weak ferromagnet
Abstract
We study the domain wall motion in a disordered weak ferromagnet, induced by injecting a spin current from a strong ferromagnet. Starting from the spin-diffusion equation describing the spin accumulation in the weak ferromagnet, we calculate the force and torque acting on the domain wall. We also study the ensuing domain wall dynamics and suggest a possible measurement method for detecting the domain wall motion via measuring the additional resistance.
