The de Haas-van Alphen effect across the metamagnetic transition in Sr${}_3$Ru${}_2$O${}_7$

R. A. Borzi, S. A. Grigera, R. S. Perry +4

We report a study of the de Haas-van Alphen (dHvA) effect on the itinerant metamagnet Sr${}_3$Ru${}_2$O${}_7$. Extremely high sample purity allows the observation of dHvA oscillations bo…
