| 中文摘要 | In magnetic measurements on Bi2Sr2CaCu2O8+delta (Bi-2212) single crystals, a general peak with a dynamical feature on both S H and S-T curves was found with S the magnetic relaxation rate. At higher fields, the characteristic exponent mu, becomes negative, together with the positive curvature of log E vs. log j and the scaling based on the 2D vortex glass (VG) theory or plastic creep theory, we conclude that the vortex motion above the second peak is plastic when j --> 0 and there is no VG phase at finite temperatures in Bi-2212. The peak of S is then explained as the crossover between different meta-stable vortex states. (C) 2003 Elsevier Science B.V. All rights reserved. |
