摘要：
Both theoretical and experimental analysis of the fluctuational magnetization of quasi-2D superconductors is performed. The obtained theoretical expression is valid in the Gaussian regime of fluctuations for arbitrary anisotropy and describes very well the presented experimental data on YBa2Cu3O7-delta while 2D or 3D scalings fail.
