摘要：
A Ba-hexaferrite/Fe composite is synthesized using a high-energy ball mill. Changes in the crystalline structure and magnetic properties are studied with the aid of X-ray diffraction and magnetization measurements. The product after an 80 h mill is magnetite (Fe3O4) and barium carbonate (BaCO3). After heating up to 1300 K in air and Ar atmospheres it is found that in the former case the product is phase M (BaFe12O19) and hematite (α-Fe2O3) with improved magnetic properties while in the second, BaFe12O19 and Fe3O4 are obtained. This is a magnetic composite material having both dipolar and exchange couplings. The coercivity observed is explained in terms of the modified Brown's equation for inverse domain nucleation fields.
