摘要：

The local magnetic relaxation in superconducting slab is investigated numerically for Anderson-Kim model, U(j) = U-c(1 - j/j(c)) and periodic potential. The relaxation of B(x, t) depends on the initial condition and the position x. B(x, t) tends to a asymptote independent of x for long time. The approximate scaling law of the relaxation of B(x, t) for some initial magnetic induction profile shows that the relaxation rate is roughly uniform over the sample. (C) 1997 Elsevier Science Ltd.
