Abstract
La-Cu substituted strontium hexaferrites with the chemical composition of Sr1âxLaxFe12âxCuxO19 were prepared by self-propagating high-temperature synthesis. The effects of La-Cu substitution on the microstructure and magnetic properties of Sr-ferrites were studied. The XRD results show that all the samples are single SrM-type phase for x<0.4. Compared with the samples without La-Cu substitution, the magnetic properties of the samples with the composition of Sr1âxLaxFe12âxCuxO19 are remarkably improved for x<0.4. The possibility that the substitution of Sr2+ by La3+ in the Sr-layer makes the Cu2+ preferably substitutes the Fe3+ in 4f2 sites is predicted to be associated with the improvement of the magnetic properties of La-Cu substituted samples.
