Abstract

The effect of Coqblin-Schrieffer-type interaction between conduction and rare-earth ion localized electrons on the superconducting order parameter δ of some ternary compounds is studied. A reentrant behavior of the order parameter is found. Superconductivity can be destroyed at two temperatures: at T c1 due to thermal pair breaking, and at T C2(< Tc1), when δ = Φ, Φ being related to magnetic ordering of rare-earth ions and spin polarization of conduction electrons.
