摘要
The vortex liquid has been studied in single-crystal YBa2(Cu1-xFex)3O7- δ in magnetic fields up to 8 T parallel to the c axis both with a dc-flux transformer-contact configuration and by measuring the c-axis resistivity. With current along the ab planes, the c-axis resistance drops to zero and the voltages on different ab planes become equal at a temperature Tbr(B). With increasing anisotropy, Tbr(B) decreased in agreement with a recent theory by Daemen et al. for a Josephson-coupled layered superconductor. The results for current injection along the ab planes and along the c axis are consistent with anisotropic local conductors for all samples. © 1995 The American Physical Society.
