摘要: The lamellar compound CuInP 2 S 6 is presented as an unusual example of a collinear, two-sublattice ferrielectric system. Single-crystal x-ray diffraction is used to study the thermal evolution of the polar character of its structure. The results are consistent with the occurrence of a first-order, order-disorder transition at T c= 315 K and provide indirect evidence for copper hopping motions. Estimates for the spontaneous polarization are calculated at various temperatures from the atomic coordinates and found to agree well with dielectric …
