Effective ferromagnetic coupling between a superconductor and a ferromagnet in LaCaMnO/Nb hybrids

D. Stamopoulos, N. Moutis, M. Pissas +1

In this work we present magnetization data on hybrids consisting of multilayers (MLs) of man- ganites [La0.33Ca0.67MnO3/La0.60Ca0.40MnO3]15 in contact with a low-Tc Nb superconduct…
