Current-driven domain walls at nonzero temperature

Rembert Duine, Utrecht University, Pays-Bas


In this talk, I will present a simple model for the dynamics of current-driven and field-driven domain walls at nonzero temperature. I will discuss various results that we have obtained using this model. These include results on average domain-wall velocities as a function of field or current, and on domain-wall depinning times. I will show how the latter results can be used to experimentally extract information on the coupling between domain walls and current.
