摘要：
Fourier-transform NMR spectra and spin-lattice relaxation rates were studied for Li-7 and P-31 in a monoclinic modification of the Li3In2(PO4)3 superionic conductor over a wide temperature range of 240-575 K. The static magnetic susceptibility of the lithium subsystem of the compound and the P-31 NMR line shape exhibit anomalous changes with increasing temperature. Quadrupole structure of the Li-7 NMR spectrum is observed under fast motion of the lithium ions in the superionic phase. In this phase the temperature behavior of the spin-lattice relaxation rates is different for Li-7 and P-31 nuclei. The results are discussed taking into account the preceding NMR data on monoclinic Li3SC2(PO4)3 and rhombohedral Li3In2(PO4)3 compounds.
