Abstract
The 4f band models of Ce-compounds have been studied, both the magnetically ordered systems and the valence mixing systems. For ordered systems, it is shown that the self-consistent band calculation of the unrestricted 1-s scheme can be done by introducing the self-interaction term. On the other hand, in valence fluctuating systems a simple and possible scheme to calculate the Fermi surface is proposed. Preliminary results for CeSb as the ordered systems and CeSn 3 as the mixed valent systems are shown.
