The anisotropic vortex dynamics and phase diagram are determined for a YBa 2 Cu 3 O 7 single crystal with columnar defects oriented at ±7.5° relative to the crystalline c-axis. A second-order splayed-glass to vortex-liquid transition is manifested for magnetic fields nearly parallel to the columns via the critical scaling of vortex AC and DC transport properties. In contrast, for magnetic fields aligned close to the ab-plane, an XY-like vortex-glass transition prevails. For magnetic fields at intermediate angles, there is no evidence of any vortex phase transition, and the vortex dynamics is described in terms of the thermally activated flux flow model.

The magnetoresistance curves of Bi(2223) thick film were measured near T c with applied magnetic field parallel and perpendicular to the c axis ranging up to 0.12 T. The results show that thermally activated flux flow region does not exist very close to T c and magnetoresistive transition can be well described by a thermally activated flux flow process below 108.5 K and at lower magnetic field. The relation between applied magnetic field H and temperature T was found to fit with “irreversibility line.”
