Abstract

To check experimentally the dispersion law of the polarization (“quasispinwave-like”) mode the characteristics of quasielastic neutron scattering at small angles are studied in KDP-type ferroelectrics. The various conceptions of the tunneling quasispin model, the nature of the low-temperature polar phase, and the vibration of tunneling particles along the axis of anisotropy are discussed with reference to the coherent neutron scattering.
