    • 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 ...
    • Development of vortex state in circular magnetic nanodots: Theory and experiment RID A-9247-2009 
      Mejia-Lopez, J.; Altbir, D.; Landeros, P.; Escrig, J.; Romero, A. H.; Roshchin, Igor V.; Li, C-P; Fitzsimmons, M. R.; Batlle, X.; Schuller, Ivan K. (American Physical Society, 2010)
      We compare magnetic reversal of nanostructured circular magnetic dots of different sizes. This comparison is based on superconducting quantum interference device (SQUID) magnetometry, neutron scattering, Monte Carlo ...
    • Effects of geometry and impurities on quantum rings in magnetic fields RID D-3014-2009 
      Aichinger, M.; Chin, Siu A.; Krotscheck, E.; Rasanen, E. (American Physical Society, 2006)
      We investigate the effects of impurities and changing ring geometry on the energetics of quantum rings under different magnetic field strengths. We show that as the magnetic field and/or the electron number are/is increased, ...
    • Interaction of mesoscopic magnetic textures with superconductors 
      Erdin, S.; Kayali, AF; Lyuksyutov, Igor F.; Pokrovsky, Valery L. (American Physical Society, 2002)
      Here we report a method to calculate the vortex and magnetization arrangement for a system of interacting superconductors and ferromagnets separated in space. The method is based on static London-Maxwell equations and the ...
