From: Field Angle Tuned Metamagnetism and Lifschitz Transitions in UPt3

Phase diagram in the field - angle plane generated from a combination of magetometry and ultrasound velocity data. Although the magnetometry data (open squares) by Suslov et al. is at ≈1 K the position of the MM transition does not change considerably between 1 K and 0.5 K, the latter being the temperature where the closed circles from US data were obtained. All the open circles and the closed circles are from the current work. The solid (green online) line represents the 1/cosθ dependence of the MM transition. The open circles mark the Lifshitz transition seen in US at 24.8 T. The hatched region represents another possible distinct state between the 24.8 LT and the 30 T transition. The solid red (online) line separating the SDWA and SDWB phases follows a cos2θ dependence.
