      Duine, R. A.; Nunez, A. S.; Sinova, Jairo; MacDonald, A. H. (American Physical Society, 2007)
      We present a microscopic treatment of current-induced torques and thermal fluctuations in itinerant ferromagnets based on a functional formulation of the Keldysh formalism. We find that the nonequilibrium magnetization ...
