Dynamics of Magnetic Domains in Current-Carrying Magnetic Superconductors

Abstract

In magnetic superconductors both superconducting and magnetic ordered phases are known to coexist under certain conditions. A simple phenomenological model is presented to study the dynamics of magnetic domains in such systems when an external current is applied. Qualitative relations between the current-induced dissipative patterns and some physical parameters are discussed numerically on the basis of the model. Especially, a possibility of bistable propagation velocities for a kink front separating both two phases is pointed out, as well as the existence of a stationary localized domain.
