9 December 1998 Systematic analysis of the critical temperature oscillations in superconducting (Nb)/spin-glass (CuMn) multilayers

The superconducting critical temperature Tc of Nb/CuMn multilayers has been measured in a series of samples with fixed Nb layer thickness (dCuMn) and varying CuMn layer thickness and vice versa, where the CuMn composition and the layer thicknesses were systematically varied. An oscillating behavior has been observed for Tc(dCuMn) strongly dependent on the Mn concentration values. Different explanations are discussed and the most plausible seems to rely on the presence of a dCuMn-dependent phase-shift value in the range (0, (pi) ) between adjacent superconducting layers.
