Abstract
We report pressure dependence of the Fermi surfaces (FSs) in CeRu2Si2 below and above the metamagnetic transition field (Hm). Below Hm, 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 Hm is much larger than that below Hm. The results are discussed in comparison with those of ferromagnetic reference material CeRu2Ge2.
