Critical Current Densities of Isolated Grain Boundaries in Coated Conductors
We report on a new technique to isolate grain boundaries (GBs) and single grains in YBa2Cu3O7-δ coated conductors using a focused ion beam microscope. The critical current density Jc of a GB measured for magnetic fields applied perpendicular to the film surface showed hysteretic behavior. For fields...
