Abstract:The angular dependence of the upper critical magnetic field, Hc2(Θ), for Nb/Pd proximity coupled multilayered nanostructures with a thickness of Nb and Pd layers of the order of the superconducting coherence length were investigated. We show that the deviation of the experimental data from the theory is temperature dependent. The performed precise analysis reveals the existence of an angular and temperature range where the deviations reach their maximum. The obtained results indicate that the parameter of the localization of the superconducting wave functions could be appropriated for describing the Hc2(Θ) curves.
