• NMR measurements have been carried out on stoichiometric /7-LiAl samples as afunction of temperature and frequency. The 'Li spin-lattice relaxation was found tobe predominantly dipolar. Data were analyzed using several diffusion models. Theresults show that a fraction of the constitutional Li vacancies in /7-LiAl is bound tothe vicinity of a Li antisite defect. The remaining free vacancies are responsible forthe fact that LiAl is a superionic Li conductor. The spin-spiu? relaxation results sup-port this picture of two different vacancy environments. The high-temperature resultsdemonstrate still another type of Li diffusion related to thermally-generated defects.
