Abstract

We observed the de Haas-van Alphen (dHvA) oscillation both in the normal and superconducting mixed states in a heavy fermion superconductor CeCoIn5. The dHvA oscillation due to a main Fermi surface is observed in the mixed state just below the upper critical field Hc2, indicating a large scattering rate of quasi-particles. We determined the Dingle temperatures both in the normal and the mixed states.
