| 概要 | The first-principles band calculation of an itinerant cerium compound CeCoSi2 is performed using a relativistic LAPW method with exchange and correlation potentials within a local-density approximation (LDA). The c-f hybridized bands with a large dispersion form two-dimensional Fermi surface (FS). The FS formation and the band dispersion including the contribution from each orbital obtained by the LDA calculation are in a qualitatively agreement with Cc 3d-4f resonant angle-resolved photoemission spectra. The LIDA calculation is a good starting point for the investigation of the electronic structure of the heavy-fermion Ce compounds. |
