The effect of bias current asymmetry on the flux-flow steps in the grain boundary YBaCuO long Josephson junctions
Journal article, 2013
The current-voltage characteristics and critical current versus magnetic field dependence of long 24 degrees[001]-tilt YBa2Cu3O7-delta bicrystal grain-boundary junctions are studied both experimentally and theoretically. For the opposite magnetic field directions, the flux-flow steps with significantly different height and slope are observed. It is demonstrated that the most probable reason of this discrepancy is recently predicted asymmetry of spatial bias current distribution due to crystallographic anisotropy of bicrystal substrates [Kupriyanov et al. JETP Lett, 95, 289 (2012)].
