| 中文摘要 | In order to investigate the vortex dynamics of a high-T-c superconductor at fields up to B-c2, single crystals of the electron doped superconductor Pr1.85Ce0.15CuO4+delta are oxygen doped in such a way that 6 T < B-c2(T=0) < 10 T. We measure the relaxation rare on an optimally oxygen doped and an oxygen overdoped sample at temperatures between 0.1 K and T-c in magnetic fields up to 7 T using high sensitivity torque magnetometry. For T similar to 0.1 K the results are compared with a quantum creep theory for the dirty limit. In the thermal regime data are analysed in terms of an activation energy U(j(s)) = (U-c/mu)[(j(c)/j(s))(mu)-1]. |
