Abstract

Magnetic properties of anisotropic M-type Sr-ferrite containing La and Co (Sr1-xLaxCoxFe12-xO19) was investigated in detail. At a composition of x = 0.3, the magnetic properties for permanent 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 %/°C.
