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

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)
We have measured the specific heat (0.3 < T < 0.6 K) of superconducting UPt3 in an external magnetic field (B< 1T) applied along the c-axis of the hexagonal crystal. We studied the field dependence of the two superconducting phases re orted before in zero field (1). The phase diagram for B//c has a
