Dimensional crossover 3D-2D-3D in superconducting layered V/Cu structures

Abstract

A temperature-dependent nonmonotonic variation of the superconducting transition width has been observed in multilayer vanadium-copper structures in a magnetic field. The critical field Hc2 was also observed to vary as a function of temperature. These variations can be attributed crossover, 3D-2D-3D, in the structure duet o the change in the temperature and the magnetic field.
