摘要：

Dissipative behavior of the flux line system in the mixed state of high temperature superconductors is studied. Difference in the magnitude of anisotropy between YBa2Cu3O7-y and Bi2Sr2CaCu2O8+y is manifest in the angular dependence of dissipation. An anomalous enhancement of disspation at high current densities is found for a narrow range of field angle near to the basal plane direction. Dissipation processes in the parallel and nearly parallel field configurations are discussed in the light of flux dynamics under the influence of strong pinning potential intrinsic to the layered structure.
