Abstract
Nonlinear I - V characteristics of YBa2Cu3Oy epitaxial film at differe nt temperatures in a magnetic field of up to 5T and angles between the direction of the field and the a - b plane of 0-degrees, 30-degrees, 45-degrees, 60-degrees, and 90-degrees were measured. We find that the re are the vortex glass phase and vortex liquid phase in the mixed sta te. The flux creep exists in the vortex glass phase, and it obviously appears in the area around the boundary between the vortex glass phase and the vortex liquid phase.
