✦ Synopsis

The effect of hybridization disorder on the normal state and the superconducting state of heavy-fermion superconductors is studied. We found this disorder can lower the characteristic temperature T k of the normal state and thus exert an indirect influence on the superconducting state. Also, this hybridization disorder turns out to have a direct pair-breaking effect on heavy-fermion superconductivity. Taking into account both the direct and indirect influences, we have consistently calculated the suppression of the superconducting transition temperature T c as a function of the effective degree of the hybridization disorder.

The superconducting phase diagram of heavy-fermion UPt 3 has been investigated by means of sensitive dilatometry. The thermodynamic analysis indicates that all the phase lines are of second order. Ehrenfest relations reveal that the C phase is the stable phase under uniaxial pressure (p II e).
