Interband pairing and superconductivity of heavy-fermion systems
Dolgov O. V., Fetisov E. P., Khomskii D. I.
The superconductivity of systems with heavy fermions is explained in a model of singlet interband pairing of the type (a/} а£ — a/{ o/t). This model gives a qualitatively reasonable description of the basic experimental properties of these systems.
