Angular Dependence of Critical Currents and Its Scaling in YBCO Coated Conductors

Angular dependent Jc in YBCO coated conductor can be explained by three different pinning mechanisms, i.e., random point pins, correlated pins along c-axis and ab-plane direction, respectively. Dependence in the intermediate angle, where the random pin is dominant, is well described by the scaling originating from the anisotropy of the coherence length.
