| 概要 | We have carried out the de Haas-van Alphen (dHvA) experiments in a valence fluctuating compound CeNi. Forty seven dHvA branches are observed experimentally, which are mainly centered at the symmetrical axes. Most of the dHvA branches are approximately explained by the 4f-itinerant band model. The cyclotron mass is in the range from 3.0 to 27 m0. Branch α, which has the largest cross-sectional area of the Fermi surface in the detected branches along the a-axis, has the cyclotron mass of 27 m0. This mass is five times larger than the corresponding band mass of 5.45 m0. |
