Resumen:
BaFe12O19 fine particles were synthesized after milling a precursor obtained as an intermediate in the sol-gel method. The samples were analyzed by X-ray di!raction, scanning electron microscopy and vibrating sample magnetometry. The milling process favors the formation of the BaM phase and therefore, provides a better speci"c magnetization and smaller grain size compared to the same preparation route but without the milling step. We report the magnetic and structural properties of the ferrite samples obtained from milled and non-milled precursors.
