Abstract
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.Keywords
