Li self-diffusion in garnet-type Li7La3Zr2O12 as probed directly by diffusion-induced Li7 spin-lattice relaxation NMR spectroscopy

Li self-diffusion in garnet-type Li7La3Zr2O12, crystallizing with tetragonal symmetry at room temperature, is measured by temperature-variable Li7 spin-spin as well as spin-lattice relaxation (SLR) nuclear magnetic resonance (NMR) spectroscopy. The SLR NMR rates which were recorded in both the laboratory and the rotating frame of reference pass through characteristic diffusion-induced rate peaks allowing for the direct determination of Li jump …
