摘要：

The mixed-state anisotropy of a YBa2CU3O7-delta Single crystal has been investigated close to T-c (T-c- T = 0.5 K) by simultaneously measuring the angular variation of the longitudinal (M(L)) and transverse (M(T)) components of the magnetization. The reversible and irreversible contributions of each component are deduced. The behaviour of the reversible magnetization vector is self-consistently analysed with the 3-dimensional anisotropic Ginzburg-Landau theory which allows us to determine all the phenomenological parameters of this superconducting compound.
