Abstract
The paramagnetic-to-antiferroparamagnetic phase transition of CeSb has been studied by high-resolution angle-resolved photoemission spectros copy. The hole and electron pockets are clearly observed at the Brillo uin-zone center and boundary, respectively. The volume of both hole an d electron pockets increases when the temperature is lowered across th e magnetic phase transition (T-N=16 K). The observed change of Fermi-s urface topology is discussed in terms of the temperature-dependent ani sotropic p-f mixing.
