摘要
The stoichiometric LixCu1-2xFe2+xO4 samples with spinel structure were obtained by standard ceramic technology and milled several hundred hours in air or liquid environment. The average size of the particles was determined by means of X-ray diffraction. The structure and magnetic properties were investigated. The magnetization, coercive field and lattice constant are changing vs milling time and chemical composition. The coercive filed increases from 3 Oe to 120 Oe, for Li0.5Fe2.5O4 sample milled 238 hours, while the specific magnetization and the lattice constant decrease vs, milling time.
