“…The appearance of asymmetry in high-T c superconducting materials with anisotropic pairing, like cuprates, has been extensively studied from experimental and theoretical points of view. In [5,6] the inhomogeneity of the critical current density due to the film growth was shown. The strong asymmetry in the displaced linear slope of the YBCO step-edge Josephson junctions was experimentally observed in [7].…”

We carry out experimental and theoretical investigations into the effect of the vortex chain propagation on the current-voltage characteristics of YBa 2 Cu 3 O 7−δ (YBCO) long Josephson junctions. Samples of YBCO Josephson junctions, fabricated on 24°[001]-tilt bicrystal substrates, have been measured. The improved technology has allowed us to observe and study the asymmetry of the current-voltage characteristics with opposite magnetic fields (Revin et al 2012 J. Appl. Phys. 114 243903), which we believe occurs due to anisotropy of bicrystal substrates (Kupriyanov et al (2013 JETP Lett. 95 289)). Specifically, we examine the flux-flow resonant steps versus the external magnetic field, and study the differential resistance and its relation to oscillation power for opposite directions of vortex propagation.

“…The inhomogeneity of the critical current density in the case of high-T c superconducting materials with anisotropic pairing, like cuprate superconductors, is the result of the film growth on the bicrystal substrate. 8,9 Unlike the artificial creation of asymmetric spatial bias current distribution in low-T c JJs using the unbiased tail for variation of the emitted power and the linewidth, [10][11][12][13][14] the natural asymmetry of spatial current distribution in grain boundary junctions (GBJs) due to crystallographic anisotropy of bicrystal substrates has been recently predicted in Ref. 15.…”

The current-voltage characteristics and critical current versus magnetic field dependence of long 24 [001]-tilt YBa 2 Cu 3 O 7Àd 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 [
