RESEARCH ON MECHANICAL ALLOYING EFFECTS ON MAGNETIC PROPERTIES OF BARIUM FERRITE TYPE M

Abstract

The paper presents the effects of mechanical alloying process of BaCO3 and αFe2O3 powders on the magnetic properties of barium ferrite type M. For preparation of the magnetic ferrite powders was used a physical method as mechanical ball milling method. The powders magnetic property was characterized with a Vibrating Sample Magnetometer. The phase’s structure was presented by an X-ray diffractometer. The morphology of the powder was observed with a particle size analyzer and a scan electron microscope. There was observed a significant increase in remanence magnetization and coercive field of barium ferrite samples obtained by mechanical alloying.
