Abstract

This paper describes the role of the substitution of La3+ and Co2+ with the formula Sr1-xLaxFe12-yCoyO19 on the magnetic properties of anisotropic strontium ferrite sintered magnets. The magnets prepared by the ceramic process have been investigated by XRD and B-H hysteresis curve measurements. Our results show that the magnetic induction coercivity (Hcb) and maximum magnetic energy product [(BH)max] of the substitution magnets [Sr1-xLaxFe12-yCoyO19 (x > y)] is notably increased without too much decreasing in the intrinsic coercivity (Hcj) and residual flux density(Br), indicating that the magnetoplumbite crystal structure may be more stable than that of Sr1-xLaxFe12-xCoxO19 magnets.
