Abstract

Nuclear magnetic resonance has been employed to study the phase transitions and microscopic structures in TlH 2 PO 4 (TDP) and TlH 2 AsO 4 (TDA) systems. The phase transitions were sensitively reflected in the rotating frame spin-lattice relaxation probing the ultra-slow microdomain motions. A prominent thermal hysteresis in the 1 H NMR- 75 As NQR cross relaxation in TDA attributed to a ferroelastic glassy nature was also observed. Besides, our high resolution 31 P NMR measurement further elucidated the nature of the microscopic environments and the phase transitions in the TDP system.
