摘要：

Measurements of the temperature and frequency dependence of the proton and deuteron spin-lattice relaxation time T1 show the presence of a dynamic central peak in paraelectric KH2PO4 which exhibits a dramatic narrowing on deuteration. The observed centralpeak narrowing on deuteration qualitatively agrees with a continued-fraction calculation demonstrating that small dynamic intrinsic clusters may occur in KH2PO4-type crystals above Tc in addition to large static defect-induced clusters observed in light-scattering experiments. © 1979 The American Physical Society.
