Abstract

We have observed the de Haas-van Alphen (dHvA) oscillation in both the normal and superconducting mixed states of CeRu2. The dHvA amplitude in the mixed state is extremely reduced for the large cyclotron orbit or the carrier with a large cross-sectional area of the Fermi surface compared to the small one. We have detected three dHvA branches, ranging from 6 × 105 Oe to 2.3 × 107 Oe. The origin of these branches is well explained by the 4f-itinerant band model.
