A relation between dielectric response and potential structure in CsH2PO4
Lei Zhang1,2, Wolfgang Kleemann1 and Wei-Lie Zhong2
Show affiliationsAccording to its relation to the dielectric response, the potential structure of CsH2PO4 can successfully be modelled either as a three-well or as a single-well potential. The deviation from the Curie-Weiss law of the dielectric response has an intimate relationship to the low central potential in the unit cells, while ordering P atoms are assumed to drive its ferroelectric phase transition.
