Abstract

Depending on the temperature and the magnitude and orientation of an external magnetic field, the critical current density, Jc, of a coated conductor can be limited either by the properties of the grain boundaries or by those of the grains. In order to ascertain what governs Jc under different conditions, we have measured straight and curved tracks, patterned into RABiTS-MOD samples, while a magnetic field was swept in the plane of the films. Significantly different results were obtained at different field and temperature ranges, which we were able to attribute to Jc being limited by either grain boundaries or grains.
