摘要：

The electronic band structure and Fermi surface are calculated for LaOS4Sb12, which is a reference material of a new heavy fermion superconductor PrOs4Sb12. The calculated Fermi surfaces consist of two closed hole surfaces around the F point and a multiply connected one. The topology of the Fermi surface is different from that in LaFe4P12 due to the larger hybridisation between Os-d and Sb-p bands. (C) 2003 Elsevier Science B.V. All rights reserved.
