Theory of the unconventional superconductivity in magnetic materials

Recent observations of superconductivity in the presence of strong paramagnetism of lanthanide and actinide materials are theoretically analyzed. The formation of superconducting electron pairs in the system of localized and delocalized electrons interacting through the Heisenberg exchange interaction is derived. The theoretical results show that the superconducting transition in magnetic materials is due to the spin-triplet pairing of electrons and exhibits an electronic analogy of the superfluid transition in 3He.
