A phenomenological modelisation of superlattices made of alternating superconducting (S) and normal (N) layers coupled by proximity effect is presented. It is shown that the anisotropy of such superconductors is not a universal quantity, but depends on external parameters such as temperature and applied magnetic fields. We also show that due to the destruction of the proximity effect in the N layers under high magnetic fields, the ration Hc2∥ Hc2⊥ is generally different from the anisotropy measured at low fields. © 1994.
