Sinitsyn, N. A.; MacDonald, A. H.; Jungwirth, T.; Dugaev, V. K.; Sinova, Jairo. (American Physical Society, 2007)The anomalous Hall effect (AHE) is a consequence of spin-orbit coupling in a ferromagnetic metal and related primarily to density-matrix response to an electric field that is off-diagonal in band index. For this reason ...

Nunner, Tamara S.; Sinitsyn, N. A.; Borunda, Mario F.; Dugaev, V. K.; Kovalev, A. A.; Abanov, Artem; Timm, Carsten; Jungwirth, T.; Inoue, Jun-ichiro; MacDonald, A. H.; Sinova, Jairo. (American Physical Society, 2007)The anomalous Hall effect in a magnetic two-dimensional electron gas with Rashba spin-orbit coupling is studied within the Kubo-Streda formalism in the presence of pointlike potential impurities. We find that all contributions ...

Jungwirth, T.; Sinova, Jairo; MacDonald, A. H.; Gallagher, B. L.; Novak, V.; Edmonds, K. W.; Rushforth, A. W.; Campion, R. P.; Foxon, C. T.; Eaves, L.; Olejnik, E.; Masek, J.; Yang, S-R Eric; Wunderlich, J.; Gould, C.; Molenkamp, L. W.; Dietl, T.; Ohno, H. (American Physical Society, 2007)We discuss the character of states near the Fermi level in Mn-doped GaAs, as revealed by a survey of dc transport and optical studies over a wide range of Mn concentrations. A thermally activated valence-band contribution ...

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 ...

Masek, J.; Kudrnovsky, J.; Maca, F.; Sinova, Jairo; MacDonald, A. H.; Campion, R. P.; Gallagher, B. L.; Jungwirth, T. (American Physical Society, 2007)A remarkable progress towards functional ferromagnetic semiconductor materials for spintronics has been achieved in p-type (Ga,Mn)As. Robust hole-mediated ferromagnetism has, however, been observed also in other III-V hosts ...

Nomura, K.; Sinova, Jairo; Jungwirth, T.; Niu, Q.; MacDonald, A. H. (American Physical Society, 2005)Spin-orbit coupling-induced spin Hall currents are generic in metals and doped semiconductors. It has recently been argued that the spin Hall conductivity can be dominated by an intrinsic contribution that follows from ...

Lee, Wei-Cheng; Sinova, Jairo; Burkov, A. A.; Joglekar, Yogesh; MacDonald, A. H. (American Physical Society, 2008)The critical temperature of an underdoped cuprate superconductor is limited by its phase stiffness rho. In this paper we argue that the dependence of rho on doping x should be understood as a consequence of deleterious ...

Garate, Ion; Sinova, Jairo; Jungwirth, T.; MacDonald, A. H. (American Physical Society, 2009)We study quantum interference corrections to the conductivity in (Ga,Mn)As ferromagnetic semiconductors using a model with disordered valence-band holes coupled to localized Mn moments through a p-d kinetic-exchange ...
