Abstract

The paramagnetic-to-antiferroparamagnetic phase transition of CeSb has been studied by high-resolution angle-resolved photoemission spectroscopy. The hole and electron pockets are clearly observed at the Brillouin-zone center and boundary, respectively. The volume of both hole and electron pockets increases when the temperature is lowered across the magnetic phase transition (TN=16 K). The observed change of Fermi-surface topology is discussed in terms of the temperature-dependent anisotropic p-f mixing.
