摘要：

The proton dynamics in TlH2PO4 (TDP) and TlH2AsO4 (TDA) was studied by means of H-1 nuclear magnetic resonance. In spite of their very similar crystal structures and phase transition sequences, these two isomorphous ferroelectrics showed distinct behaviors in proton motions through the ferroelastic phase transition temperature. Our results may be understood in terms of the coupled hydrogen-lattice model and are associated with distortion of the PO4 (-)/AsO4- tetrahedra.
