Abstract

Angular dependent critical current densities J_c(H,θ) for the YBa₂Cu₃O_7-y/Pr_0.5Y _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. J_c(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.
