  • Abstract
    The authors report on investigation of magnetic aftereffects in ceramic BaO.-nFe2O3 ferrites up to 300 K in the time and frequency domains. The relaxation phenomena observed below the Verwey temperature are identified with electronic processes which have been found in magnetite. These relaxation phenomena strongly depend on the concentration of barium ions and on the firing and cooling gas atmosphere conditions used in the sintering of the ferrites
