Abstract

Applying the method of beta -radiation detected nuclear magnetic resonance/relaxation ( beta -NMR) to 8Li nuclei in 7Li3N single crystals comprehensive information on static and dynamic properties was obtained. Below T approximately=200 K the electric field gradients (EFG) at the two inequivalent Li lattice sites (Li(1), Li(2)) were determined. The spin-lattice relaxation (SLR) behavior above T approximately=300 K and the 8Li NMR signals in the extreme narrowing regime (T>or=500 K) could be attributed to interlayer diffusion involving Li+ jumps between Li(1) and Li(2) lattice sites ((1 to or from 2) jumps). In the temperature range 200 K<or=T<or=300 K the transients of the 8Li(1) and 8Li(2) polarizations were measured separately by applying a special radio frequency scheme. The different SLR behaviour allowed us to study the Li+ intralayer diffusion confined to the Li2N layers. Furthermore, ultra-slow interlayer (1 to or from 2) jumps with correlation times of up to 10 s were observed in this T region. Below 200 K a nonexponential 8Li polarization decay depending weakly on B and T was observed. The SLR in this T range is discussed in terms of statistically distributed relaxation centres.
