Figure 7. (A) ⁷Li NMR line widths δ of the central line of tetragonal LLZO versus temperature. The dashed line represents a fit according to Equation (2) with no restrictions for the adjustable parameters. The solid line shows the same fit, however, with E_a being fixed at 0.5 eV. ⁷Li NMR; (B) SLR rates and; (C) SSR rates of tetragonal LLZO recorded in both the laboratory (•) and the rotating frame of reference (◦).
