Indirect RKKY exchange and magnetic states of layered ferromagnet-superconductor structures
Khusainov M. G.
The long-range antiferromagnetic contribution to RKKY exchange between localized spins which stems from the transition of a metal to a superconducting state strengthens toward the surface of a bulk sample or as the dimensionality of the sample is lowered. Several versions of a mutual accommodation of superconductivity and ferromagnetism in layered ferromagnet-superconductor structures are discussed.
