Study of strontium ferrites substituted by lanthanum on the structural and magnetic properties

M-type strontium ferrites, Sr 0.8La 0.2Fe 12O 19 have been synthesized by conventional ceramic process. The effects of lanthanum addition and sintering temperature on microstructures and magnetic properties of SrFe 12O 19 and Sr 0.8La 0.2Fe 12O 19 samples were investigated. Microstructural analysis...
