Abstract

The morphology, structure parameters, and magnetic characteristics of mechanically alloyed magnetite and cobalt and magnesium spinel-ferrite nanopowders are investigated. The effect of the nanopowder particle size on the saturation magnetization of the spinel ferrites and the roles of the surface anisotropy and magnetoelastic energy in the formation of the magnetic anisotropy of the materials under study are discussed within the framework of a core-shell model.
