Drastic change of the Fermi surface across the metamagnetic transition in CeRh${}_2$Si${}_2$

K. Götze, D. Aoki, F. Lévy-Bertrand +2

We report high field de Haas-van Alphen (dHvA) effect measurements in CeRh${}_2$Si${}_2$ both below and above the first-order 26 T metamagnetic transition from an antiferromagnetic to…
