Angular dependence of the upper critical field and the critical current density for Y1Ba2Cu3O7−δ films

Resistive measurements for the angular dependence of both Bc2 and Jc were performed using high-Jc Y1Ba2Cu3O7−δ films prepared by chemical vapor deposition. The angular dependence of Bc2 was described by the anisotropic Ginsburg-Landau theory with different masses for in-plane and out-of-plane. We found that the angular dependence of Bc2 largely contributes to the anisotropic Jc on the basis of the flux pinning scaling law.
