โœฆ Synopsis

To understand the double superconducting (SC) transitions and the isotropy of the phase diagram H vs T in a heavy Fermion compound UPh, we develop a scenario based on the one-dimensional representation (ID-REP) with odd-parity in the case of weak spin-orbit coupling. A symmetry breaking field due to the antiferromagnetism (T N = 5 K) lifts the spin space degeneracy to split T c. The 1D-REP scenario explains the experiments better than the previous 2D-REP scenario. A nontrivial vortex is predicted to appear at lower fields.

Recent small angle neutron scattering experiments under an external field H by Kleiman et al. reveal that in UPt3 a distorted vortex lattice is stabilized and the rhombic unit cell angle ct(H) varies continuously with increasing H applied perpendicular to the hexagonal c-axis.

The specific heat of several poly-and single-crystalline samples of UPt, and UPt,B, 1, has been measured below 1 K. in order to study the substructure in the anomaly below the superconducting transition. A double anomaly has been observed for Czochralski-grown single-crystalline UPt, as well as for
