Abstract

We report pressure dependence of the Fermi surfaces (FSs) in CeRu₂Si₂ below and above the metamagnetic transition field (H_m). Below H_m, the dHvA frequencies arising from hole FSs decrease by 20% on application of 6 kbar, while that from an electron FS increases by 10%. The pressure dependence of the frequencies above H_m is much larger than that below H_m. The results are discussed in comparison with those of ferromagnetic reference material CeRu₂Ge₂.
