    摘要

    Angular dependent critical current densities Jc(H,θ) for the YBa2Cu3O7-y/Pr0.5Y 0.5Ba2Cu3O 7-y(120Å/24Å)×8 superlattice under various magnetic fields were measured to investigate the influence of the applied magnetic fields on the dimensionality of the flux pinning and flux dynamics. Jc(H,θ) was obtained by applying current through x- or y- direction and analyzed by Kes model. It is found that the dissipation of the flux line system in the mixed state is mainly due to the pancake motion along ab-plane as H < 1 T, while the flux lines begin to move along c-axis when the magnetic field reached 1 T. The causes will be discussed.
