摘要：

We report the measurements of the de Haas-van Alphen (dHvA) effect for field ranges below and above the metamagnetic transition field (H(m)) in CeRu2Si2. The dHvA frequency branches and the effective masses ranging from 1.5m0 to 120m0 observed below H(m) agree with the predictions of the itinerant f electron model, whereas those above H(m) can be explained well with the localized f electron model. All the dHvA frequencies change abruptly around H(m). The effective masses decrease considerably around H(m) and then continue to decrease with increasing field.
