Abstract
Based on an improved calculation formalism of the proximity effect, the transition temperature Tc, the parallel (Hc2∥) and perpendicular (Hc2⟂) critical fields of the Nb50Ti50/Nb superlattice have been analyzed as a function of the structural modulation wavelength λs. Tc, Hc2∥ and Hc2⟂ have been calculated using a unified set of the material parameters and allowing for the transition of the center of the order parameter between the NbTi and Nb layers. The calculation has systematically reproduced the characteristics of Hc2∥ and Hc2⟂ including the two-step dimensional crossover of Hc2∥(T) and the anomalous upward curvature of Hc2⟂(T).
