Structural features associated with two types of dimensional transitions have been detected for the first time on the temperature and angular dependence of the upper critical field, Hc2 (Τ,θ) (θ is the angle between the magnetic field and the plane of the supperlattice), and on that of the critical current, IC(T), for model samples of layered superconductors. These structural features are evidence of a localization of the order parameter.
