説明

X-ray diffraction studies at low temperatures have been performed in order to investigate thermal properties of crystal lattices in the low-carrier-density systemscerium monopnictides. CeP and CeAs show large crystal-lattice contractions with increasingtemperatures up to about 120, K and 90, K, respectively. Due to the strong p-f mixing, theexcited crystal fieldΓ8-like state is expected to produce a shorter interatomic bond length betweencerium ions and neighboring pnictogens than that realized by the Γ7 ground state.The experimental results of the lattice contractions at low temperatures are explained bythe thermal average of these crystal field states.
