Abstract
We present a study of the intermediate and final phases during mechanosynth esis of ZnFe2O4. Mossbauer measurements at T = 4.2 K indicate creation of o xygen vacancies and local disorder at Fe sites during milling. Magnetizatio n data show lack of saturation and irreversibility at high fields. Our data is qualitatively well described by a model of particles with a magnetic or dered core coupled to a spin-disordered surface layer. (C) 1999 Published b y Elsevier Science B.V.
