✦ Synopsis

Recent results of several experimental studies on the superconducting behaviour of UPt, are reviewed. Special attention is given to the qualitative features: 1) the existence of two transitions at H = 0 and the phase diagram under a magnetic field applied both parallel (N//c) and perpendicular (Hlc) to the hexagonal axis, established by specific heat measurements, 2) the suppression of the high-temperature phase by a small hydrostatic pressure.

  1. the reversal of the hitherto apparent correlation between the strength of the electron-electron interactions in the normal state and the onset of superconductivity, when investigated for each crystallographic axis separately by means of uniaxial stress and 4) the sharp break in the slopes of both the critical fields H,,(T) and H,,(T) for Hlc.

The heavy-fermion superconductor UPt 3 shows many indications of unconventional superconductivity. In particular, the multiplicity of superconducting phases calls for an explanation in terms of a multi-component order parameter. As will be reviewed in this article, these phases have been mapped out

The electronic instability in the highly correlated electron system UPt 3 gives rise to various intriguing phenomena at liquid-helium temperatures, among which the occurrence of unconventional superconductivity (T + = 0.49 K, T c = 0.44 K) has attracted most attention. In a magnetic field three supe
