Short-range ordering and freezing in a randomly mixed ferroelectric-antiferroelectric crystal
Abstract
X-ray measurements on single-crystals of Rb_(1−x)(NH_4)_xH_2PO_4 trace the development of a glasslike state. The absence of macroscopic crystal-symmetry change during freezing is confirmed, while diffuse scattering reveals the growth of very-short-range order. The latter coincides with a compressibility anomaly seen in Brillouin scattering and with dielectric effects suggesting freezing. The system is in many ways analogous to spin-glasses.

Pytte for helpful discussions, as well as P. Bayer for his careful growth and cutting of the fragile single-crystal platelets. One of us (S.E.N.) was supported by a Natural Science and Engineering Research Council of Canada fellowship.Attached Files
