High-Performance Ferrite Magnets : M-Type Sr-Ferrite Containing Lanthanum and Cobalt

Abstract

Magnetic properties of anisotropic M-type Sr-ferrite containing La and Co (Sr_<1-x>La_xCo_xFe_<12-x>O_<19>) was investigated in detail. At a composition of x=0.3, the magnetic properties for pemanent magnets were much improved, with the highest values of Br=4.45 KG, HcJ=4.82 kOe, and (BH)_<max>=4.86 MGOe. The temperature dependence of the coercivity was also much improved, with ΔHcJ/HcJ/ΔT=0.1%/℃.
