摘要：

Ba-hexaferrite has been prepared by mechanical alloying and subsequent heat treatment. Powders were studied by X-ray diffraction, transmission electron microscopy, Mossbauer spectroscopy and magnetic measurements. High coercivities of up to 6 kOe were measured for these fine-particle materials.
