Ionic Motion in Solid Electrolytes: A Solid State NMR Study of Sodium and Lithium in β-Alumina
<p>Solid state NMR techniques have been used as a microscopic probe of the structural and dynamical properties of the mobile cations in the solid electrolyte β-alumina. The first order quadrupole shifts in the (±3/2 ↔ ±1/2) transitions in the spin 3/2 nuclei sodium and lithium have allowed the...
