Abstract
We have made measurement of ac susceptibility to study the effects of ac field orientation on flux creep of textured YBa2Cu3O7. The data are analyzed based on the nonlinear flux diffusion equation. It is found that the effective activation barrier and velocity scale of flux diffu sion are anisotropic. This work also demonstrates that the extra advan tage of ac susceptibility experiments for study of flux relaxation.
