Observation of strong to Josephson-coupled crossover in 10° YBa2Cu3Ox bicrystal junctions

A temperature-dependent strong to weak (Josephson) coupling crossover near 75 K is observed for 10° misorientation YBa2Cu3Ox grain boundaries. Below 75 K the current–voltage characteristic (IVC) shows strongly coupled, flux-flow behavior. Above 75 K, the IVC is Josephson coupled. The data are consis...
