| Research Abstract |
In the f-electron compounds, conduction electrons moving around freely in the crystal hybridize relatively localized f-electrons, to bring very interesting and distinctive properties, such as heavy electron, multipole ordering, and anisotropic superconducting. In this research, we have performed Fermi surface study for synthesized diluted samples and new novel materials, combined with band theory and de Haas-van Alphen measurement, to clarify how the heavy fermions are born and a variety of heavy electron system.
