Y. Tomita et al., STRUCTURE AND DYNAMICS OF LI3INBR6 AND NAINBR4 BY MEANS OF NUCLEAR-MAGNETIC-RESONANCE, Zeitschrift fur Naturforschung. A, A journal of physical sciences, 53(6-7), 1998, pp. 466-472
Li3InBr6 and NaInBr4 have been synthesized and characterized by means
of DTA, Br-81 NQR, Li-6, Li-7, Na-23, and In-115 NMR, and AC conductiv
ity. These measurements revealed the presence of phase transitions and
cationic diffusion in both compounds. From the spin-lattice relaxatio
n times of Br NQR and the peak widths of Li-7 and Na-23 NMR spectra, i
t is deduced that the conduction is due to cationic diffusion. The act
ivity energy for the Li+ diffusion was found to be 24 kJ/mol for Li3In
Br6.
