摘要：
Nanocrystalline Zn-Mn spinel ferrites have been obtained by high-energy ball milling from precursor oxides and carbonates (1) and hydroxides and oxides (2), From the measurement of initial magnetic permeability as a function of temperature, differences in chemical homogeneity have been observed. Structural and Curie point data reveal that dissolution of Mn2+ into the spinel structure is assisted by the presence of a hydroxide and an acid oxide. For fixed milling conditions, the influence of precursors leads to different chemical, structural, and magnetic properties in ferrites obtained by mechanochemical synthesis. (C) 1998 Academic Press.
