Stimulation of superconductivity in multilayer niobium structures
Dedyu V. I. , Lykov A. N.
The critical temperature is found to increase with increasing number of layers in a multilayer niobium-based superconducting structure. The temperature dependence of a parallel critical magnetic field reveals a deviation from the square-root law. The results can be explained by an increase in the amplitude of the order parameter in the layers due to a weak Josephson coupling between them.
