Transition temperature of a superconductor-ferromagnet superlattice
Buzdin A. I. , Kupriyanov M. Yu.
A method is proposed for calculating the transition temperature Tf of a superconductor-ferromagnet (SF) superlattice. It is shown that Tf of ariSF superlattice oscillates with the thickness of the F layer and with the strength of the exchange field. States with a phase order parameter, which varies from layer to layer, are possible in this superlattice.
