Abstract: Spin alignment echo (SAE) is employed here to study the α-LiAsF6/PEO6 system with low poly(ethylene oxide) (PEO) molecular weight. We show that the correlation rate kSAE from SAE experiments, but not the spin-lattice relaxation time and the linewidth, is a better indicator to characterize the higher conductivity.

Key words: spin alignment echo (SAE), polymer electrolyte, linewidth, spin-lattice relaxation time
