Abstract

We report ultrasonic velocity measurements on two UPt3 samples with three different field orientations (H⊥c, H∥c and H//c=45°). Velocity changes are observed at constant temperatures, as the field is swept, at the upper critical field Hc2 and at the flux lattice transition Hfl. Velocity changes are also observed at Tc+ the upper transition temperature and Tc- the lower transition temperature as the temperature is swept at constant fields. Complete phase diagrams for UPt3 obtained by a single measurement technique on the same samples in the H-T plane are presented.
