Structural and magnetic properties of an anisotropic M-type LaCo-substituted strontium hexaferrite

Résumé

Rare-earth-free permanent magnets returned to the forefront of scientific and technological concerns about the environmental and economical issues. The emergence of new markets, control of costs and availability of raw materials encourage to look for alternative materials containing much less, or no, rare earth elements selected from the most common and most available. The hexaferrite doped with lanthanum and cobalt present interesting properties to succeed the rare-earth magnets. The structural and magnetic properties of a strontium hexaferrite are presented in this paper, and two models are developed in order to correlate structural and magnetic properties.
