Abstract
The measurements of critical temperature and critical magnetic fields were carried out in superconducting Ni/Pb modulated films. These films consisted of thick Pb component layers (dpb = 400 Å) and thin layers of Ni with thickness dNi ranging from 8 Å to 30 Å. The dependence of critical temperature on the thickness of Ni component layers was compared with theoretical model. Our measurements of parallel critical field as a temperature function did not give any evidence of dimensional crossover of superconductivity induced by temperature.
