    • Functional Keldysh theory of spin torques 
      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 ...
    • Local control of magnetocrystalline anisotropy in (Ga,Mn)As microdevices: Demonstration in current-induced switching 
      Wunderlich, J.; Irvine, A. C.; Zemen, J.; Holy, V.; Rushforth, A. W.; De Ranieri, E.; Rana, U.; Vyborny, K.; Sinova, Jairo; Foxon, C. T.; Campion, R. P.; Williams, D. A.; Gallagher, B. L.; Jungwirth, T. (American Physical Society, 2007)
      The large saturation magnetization in conventional dense moment ferromagnets offers a flexible means of manipulating the ordered state through demagnetizing shape anisotropy fields, but these dipolar fields, in turn, limit ...
