Interorbital pairing for heavy fermions and universal scaling of their basic characteristics

We show that the properties of the heavy-electron superconducting state induced by the interorbital kinetic exchange scale with the effective-mass renormalization m*/m0∼1/TK. Explicitly, the pairing potential J∼J(m0/m*)ln2(m0/m*), where J is the magnitude of the bare Kondo coupling; the coherence length ξ∼TK/Tc, where Tc is the transition temperature, whereas the penetration depth λ∼(m*/m0)1/2 so that λ/ξ much-gt 1. We also determine the scaling of magnetic critical fields
