## Abstract We report the structural characterization and magnetic behaviour of the spinels with general formula Li~0.5+0.5~~__x__~Fe~2.5−1.5~~__x__~Ti~__x__~O~4~, where __x__ = 1.28 and 1.50. When the samples are cooled slowly, a 1:3 crystallographic order occurs, whereas a random disorder is obse
