Fermi Surface Variation of Ce 4f-electrons in Hybridization Controlled Heavy-Fermion Systems

H. J. Im, T. Ito, H. Miyazaki +6

Ce 3d-4f resonant angle-resolved photoemission measurements on CeCoGe${}_{1.2}$Si${}_{0.8}$ and CeCoSi${}_2$ have been performed to understand the Fermi surface topology as a function…
