摘要：

Co-Mn ferrites with a nominal composition LixCo0.5Mn0.5-xFe2O4 (0.0 <= x <= 0.3) are prepared by calcining precursor oxalates in air. The effects of composition and calcination temperatures on their structure, morphology, and magnetic properties are studied. A high-crystallized LixCo0.5Mn0.5-xFe2O4 with a cubic structure is obtained when the precursor is calcined at 950 degrees C in air for 3 h. All the Li+ substituted Co-Mn ferrites exhibit typical spinel structure. Moreover, lattice parameters of LixCo0.5Mn0.5-xFe2O4 decrease and crystallite size increases with increasing Li+ content, leading to an increase of the specific saturation magnetization and a decrease of the coercive field and the magnetic anisotropy constant.
