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).

The following issues concerning UPd2A13 are addressed: (i) its anisotropic magnetic phase diagram which can be explained by domain-reorientation effects, (ii) the coexistence between magnetically ordered local 5f moments and Cooper pairs formed by weakly delocalized 5f states and (iii) distinct anom

Point-contact spectroscopy has been used to study the superconducting properties of the heavy-fermion system UPt~ down to about .40 inK. The differential resistance of heterocontacts between UPt3 and Pt shows, for current flow parallel to the c direction, a distinct minimum at a low bias due to Andr
