N2 - We have succeeded in growing high-quality single crystals of CeRu2 and have measured the magnetoresistance and de Haas-van Alphen (dHvA) effect in both its normal and its superconducting mixed states. From the result of the magnetoresistance, we conclude that CeRu2 is a compensated metal. The measured dHvA frequencies are well explained by the results of band-structure calculations. The dHvA frequency does not change in magnitude between the normal and superconducting mixed states, while the cyclotron mass is reduced, and the corresponding Dingle temperature increases in the mixed state. The mass and the Dingle temperature strongly depend on the magnetic field in the mixed state.
