Abstract
The effects of prolonged milling in air and vacuum on BaFe12O19 ionic crystal structure and particles morphology have been analysed. X-ray d iffraction, scanning electron microscopy and thermal analysis experime nts show that for vacuum-milled material the ordered structure transfo rms progressively into a stable disordered nanocrystalline phase. For air-milled samples, apart from structural transformation, chemical dec omposition was found.
