    • Angular-Dependence of the Critical Current in Layered Superconductors 
      Pokrovsky, Valery L.; Lyuksyutov, Igor F.; NATTERMANN, T. (American Physical Society, 1992)
    • Anisotropic transport properties of ferromagnetic-superconducting bilayers 
      Kayali, MA; Pokrovsky, Valery L. (American Physical Society, 2004)
      We study the transport properties of vortex matter in a superconducting thin film separated by a thin insulator layer from a ferromagnetic layer. We assume an alternating stripe structure for both FM and superconducting ...
    • Antiferromagnetic domain size and exchange bias 
      Fitzsimmons, M. R.; Lederman, D.; Cheon, M.; Shi, H.; Olamit, J.; Roshchin, Igor V.; Schuller, Ivan K. (American Physical Society, 2008)
      Using neutron diffraction, we measured the sizes of antiferromagnetic domains in three ferromagnet/antiferromagnet bilayer samples as a function of the magnitude and sign of exchange bias, temperature, and antiferromagnet ...
    • Creation and pinning of vortex-antivortex pairs 
      Kim, Sangbum; Hu, Chia-Ren; Andrews, Malcolm J. (American Physical Society, 2006)
      Computer modeling is reported about the creation and pinning of a magnetic vortex-antivortex (V-AV) pair in a superconducting thin film, due to the magnetic field of a vertical magnetic dipole above the film, and two antidot ...
    • Disorder-induced magnetic memory: Experiments and theories RID F-6415-2010 RID C-4384-2008 RID B-1163-2008 RID A-3020-2010 
      Pierce, M. S.; Buechler, C. R.; Sorensen, L. B.; Kevan, S. D.; Jagla, E. A.; Deutsch, J. M.; Mai, T.; Narayan, O.; Davies, J. E.; Liu, Kai; Zimanyi, G. T.; Katzgraber, Helmut G.; Hellwig, O.; Fullerton, E. E.; Fischer, P.; Kortright, J. B. (American Physical Society, 2007)
    • Faceting via correlated disorder of a stochastically growing interface or domain boundary 
      Lyuksyutov, Igor F.; Everts, HU. (American Physical Society, 1998)
      We consider a stochastically growing or evaporating interface in the presence of disorder which is correlated in the direction normal to the interface. The growth or evaporation rate at randomly distributed disorder points ...
    • Magnetization relaxation in (Ga,Mn)As ferromagnetic semiconductors 
      Sinova, Jairo; Jungwirth, T.; Liu, X.; Sasaki, Y.; Furdyna, JK; Atkinson, WA; MacDonald, AH. (American Physical Society, 2004)
      We describe a theory of Mn local-moment magnetization relaxation due to p-d kinetic-exchange coupling with the itinerant-spin subsystem in the ferromagnetic semiconductor (Ga,Mn)As alloy. The theoretical Gilbert damping ...
    • Steady-state and equilibrium vortex configurations, transitions, and evolution in a mesoscopic superconducting cylinder 
      Kim, S.; Hu, Chia-Ren; Andrews, MJ. (American Physical Society, 2004)
      A numerical scheme to study the mixed states in a mesoscopic type-II superconducting cylinder is described. Steady-state configurations and transient behavior of the magnetic vortices for various values of the applied ...
    • Systematics of Pure and Doped He-4 Clusters 
      Chin, Siu A.; KROTSCHECK, E. (American Physical Society, 1995)
      Optimized variational calculations have been carried out for pure and doped clusters of He-4 atoms up to a cluster size of N=1000 particles. For small cluster sizes with less than or equal to 112 particles, where comparisons ...
    • Theory of weak localization in ferromagnetic (Ga,Mn)As 
      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 ...
