Abstract
The proton dynamics in TlH2PO4 (TDP) and TlH2AsO4 (TDA) was studied by mean
s of H-1 nuclear magnetic resonance. In spite of their very similar crystal
structures and phase transition sequences, these two isomorphous ferroelec
trics 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 P
O4 (-)/AsO4- tetrahedra.
