Theory of the unconventional superconductivity in magnetic materials

Recent experimental observations of superconductivity in the presence of strong paramagnetism of lanthanide and actinide materials are theoretically analysed. The formation of superconducting electron pairs in the system of localized and delocalized electrons interacting through the Heisenberg exchange interaction is derived. Theoretical results show that the superconducting transition in the magnetic materials is due to the spin-triplet pairing of the electrons and exhibits the electronic analogy of the superfluid transition in³He.
