Résumé

The influence of the two-gap/two-band superconductivity on the anisotropy properties of MgB₂ is discussed. It is shown that due to the different anisotropies and different field sensitivities of both bands the lower critical field H_c1 and the upper critical one H_c2 reveal very different and temperature-dependent anisotropies. The deviations of the angular dependence of H_c2 (Θ) from the classical form is discussed in the framework of the two-band model.
