Abstract

The characteristics of magnetic domain-wall depinning driven by a spin transfer torque are dramatically different compared to those driven by a conventional magnetic field. By using the recently derived formalism of the spin torque, we describe key features in the dynamics of geometrically confined domain walls. We numerically calculated the pinning-depinning phase boundary in the presence of the external field and the current.
