摘要: | Recent experiments in Bi(2)Sr(1)Ca(1)Cu(2)O(8+delta) [7] demonstrated that the fluctuation diamagnetism in strong magnetic field at the vicinity of the critical temperature significantly differs from the behavior predicted by fluctuation diamagnetism theories based on Ginzburg-Landau model within the lowest Landau level approximation. In this study, we extend previous theoretical result to the T < T(c) region and incorporate to the theory contributions from higher Landau levels. Comparison with experimental results shows a good agreement with the theory for an optimally doped sample, while for under-doped sample the agreement is poor at low temperature. |
