摘要：

The vortex liquid in highly oriented melt-textured YBa2Cu3O7:Y2BaCuO5 (123:211) with H parallel to c up to 10 Tesla is investigated through in-plane and out-of-plane transport measurements. A reduced c-axis vortex correlation with respect to the single crystal case is detected in pseudo-flux-transformer experiments. Results an interpreted on the basis of the effects of the competing consequences of correlated disorder due to twin boundaries and non-correlated disorder provided by the randomly distributed sub-micrometric 211 phase in the 123 matrix.
