摘要：
The current-voltage characteristics (CVC's) of YBa2Cu3O7-delta epitaxial film were determined at various temperatures and magnetic fields. The pinning potential U-0(T, H), critical current density J(c)(T, H) and effective pinning potential U-eff(H, T, J) were derived from the CVC's. It is shown that the nonlinear response regime of the vortex-liquid (NRVL) display a changing process from vortex plastic creep to free flow with the dynamic exponent changing from -0.5 to 0.
