Abstract

The dynamics of the ZnCl₄ tetrahedra in the ferroelectric lock-in phase of K₂ZnCl₄ was studied by means of pulsed ³⁵Cl NQR. (nuclear quadrupole resonance) techniques. From the temperature dependence of the spin-lattice relaxation rate (1/T_1Q) for each of the triplicated Cl(1) sites in the lock-in phase, it is suggested that the domain peak in the incommensurate phase arises from the ZnCl₄ tetrahedral site with a negligible reorientational motion, whereas the other two sites with an activated reorientational motion lead to the phase solitons.
