Abstract

We have studied phase transitions in TlH2AsO4 using 200 MHz 1H pulsed NMR. The rotating frame spin-lattice relaxation data fitted the stretched-exponential type, M(t)=M0exp[-(t/T1ρ)1-n], below the ferroelastic phase transition temperature, and double-exponential type above that temperature. The exponent n behaved as an order parameter.
