Abstract

We have performed the de Haas-van Alphen effect study under high pressure for both the field ranges below and above the metamagnetic transition field (Hm) in CeRu2Si2. The effective masses below Hm decrease considerably with pressure as expected from various macroscopic measurements, whereas above Hm it is found that the effective mass for the large hole surface does not change substantially with pressure. The dHvA oscillations can be traced all the way from below to above Hm and it is found that the transition of the dHvA oscillations takes place in a narrower field range than the transition width of magnetization.
