Phase diagram of superconductor-ferromagnet superlattices

Z. Radović, L. Dobrosavljević-Grujić

Open publisher page 2 citations

Abstract

Recent progress in the proximity effect theory of superconductor-ferromagnet superlattices is reviewed. The phase diagram calculations, transition temperature Tc and upper critical fields (formula available in paper), are presented. Characteristic features in Tc and Hc2(T) dependence on layers thicknesses, including the predicted unusual oscillatory variations and new inhomogeneous superconducting state with nontrivial phase difference between neighboring superconducting layers, are discussed and compared with experimental data for V/Fe and Nb/Gd superlattices.
