Magnetoresistance Oscillations in Granular Superconducting Niobium Nitride Nanowires
U. Patel, Z. L. Xiao, A. Gurevich +5
We report on magnetoresistance oscillations in superconducting NbNx nanowires synthesized through ammonia gas annealing of NbSe3 precursor nanostructures. Even though the transvers…
Probing multi-band superconductivity and magnetism in SmFeAsOF single crystals by high-field vortex torque magnetometry
L. Balicas, A. Gurevich, Y. J. Jo +9
To probe manifestations of multiband superconductivity in oxypnictides, we measured the angular dependence of magnetic torque in the mixed state of SmOFFeAs…
Size effects in the nonlinear resistance and flux creep in a virtual Berezinskii-Kosterlitz-Thouless state of superconducting films
A. Gurevich, V. M. Vinokur
We show that the size effects radically affect the electric field-current () relation of superconducting films. We calculate due to thermally-activated hopping of singl…
Dendritic flux avalanches and nonlocal electrodynamics in thin superconducting films
Igor S. Aranson, Alex Gurevich, Marco S. Welling +4
We present numerical and analytical studies of coupled nonlinear Maxwell and thermal diffusion equations which describe nonisothermal dendritic flux penetration in superconducting…
Thickness dependence of critical currents in thin superconductors
A. Gurevich
Mechanisms of vortex dynamics and pinning and self-field effects which could account for the thickness dependence of the critical current density J_c of superconducting films are a…
