The temperature dependence of the 7Li spin-lattice relaxation time in the temperature interval 170–340 K has been studied in undoped and proton-exchanged powder specimens of LiNbO3. An anomaly in the temperature behavior of the relaxation time T1 in the temperature interval 300–340 K is revealed in...
