摘要: We investigate supercurrent-induced magnetization dynamics in a Josephson junction with two misaligned ferromagnetic layers and demonstrate variety of effects by solving numerically the Landau-Lifshitz-Gilbert equation. In particular, we possibility obtaining switching for an experimentally feasible set parameters, clarify favorable condition realization reversal. These results constitute superconducting analog to conventional current-induced indicate how spin-triplet supercurrents may be utilized practical purposes spintronics.
