Field induced Lifshitz transition in UPt${}_2$Si${}_2$: Fermi surface under extreme conditions

D. Schulze Grachtrup, N. Steinki, S. Süllow +6

We have measured Hall effect, magnetotransport and magnetostriction on the field induced phases of single crystalline UPt${}_2$Si${}_2$ in magnetic fields up to 60\,T at temperatures d…
