  • Abstract
    Magnetic after-effect and induced uniaxial anisotropy investigations have been carried out on lithium ferrite polycrystalline samples of initial compositions Li0.5+xFe2.5-xO4( -0.05 \\leq x \\leq 0. 10 ). A directional order phenomenon has been observed, which is attributed to the migration of interstitial lithium. This phenomenon is characterized by an after-effect band at about 240°K and the creation of an uniaxial anisotropy of about 90 erg/cm3, which corresponds to 2.5×1019interstitial lithium per cubic centimeter.
