Use of beta radiation-detected NMR to study ionic motion in solids

verfasst von: Paul Heitjans
Abstract: The method of beta radiation-detected nuclear magnetic resonance/relaxation (β-NMR) is introduced and its features and capabilities as a new tool for studying ionic motions on a microscopic scale are discussed. Information on ion dynamics is obtained from spin-lattice relaxation rates and resonance spectra of isolated β-active nuclei embedded in the sample. The polarized probe nuclei are produced by a nuclear reaction. Their polarization is monitored via the anisotropy of the β-radiation distribution. Recent applications to the field of solid state ionics are reviewed. As examples of β-NMR on solids with a layer structure measurements on the fast ionic conductor Li₃N and the intercalation compound LiC₆ are discussed. Emphasis is on the questions of low-dimensional diffusion. We further discuss lithium silicate and borate glasses as representatives of strongly disordered solids. Different modes of ionic motion were found by spin-relaxation measurements over wide temperature and magnetic field ranges. We deal also with the low-temperature data which reflect the influence of defect centres typical of glasses.
