Kurzfassung:
The temperature dependences of the NMR relaxation times of 7 Li in K 3 LiNb 6 O 17 (KLN–2) and K 3 LiTa 6 O 17 (KLT–2) are reported. The logarithms of the relaxation times give straight lines against the inverse temperature, and the activation energies are estimated to be 0.29 eV and 0.33 eV from the longitudinal relaxation times for KLN–2 and KLT–2, respectively. The motion of Li ions observed by NMR is discussed in connection with the ionic conduction in these materials and it is shown that the relaxation process is due to short-range ionic motion.
