Influence of a Uniform Current on Collective Magnetization Dynamics in a Ferromagnetic Metal

J. Fernandez-Rossier, M. Braun, A. S. Núñez +1

We discuss the influence of a uniform current, $\vec{j}$, on the magnetization dynamics of a ferromagnetic metal. We find that the magnon energy $\epsilon (\vec{q})$ has a current-induced…
