Nuclear Magnetic Resonance Study of 23Na in NaMgCl3 Single Crystal Yeom, Tae Ho;
We have investigated nuclear magnetic resonance of nucleus in single crystal in the temperature range 200 K~410 K using FT-NMR spectrometer. The spin-lattice relaxation times of nucleus residing at cubic symmetry in the host crystal was measured as a function of temperature. The of nucleus decreased with increasing temperature. The nuclear spin-lattice relaxation rate of in single crystal was proportional to the temperature T. This behavior is explained with the characteristic feature of the direct process between the nuclear spins and single phonon, being proportional to the absolute temperature. The activation energy calculated was .
