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 (Formula presented). The observed change of Fermi-surface topology is discussed in terms of the temperature-dependent anisotropic (Formula presented) mixing.
