Structural and magnetic properties of Ce 3+ -substituted Sr-ferrites synthesized by low-temperature calcination ceramic method

Ce 3+ -substituted Sr-ferrite powder was synthesized through low-temperature calcination ceramic method. The influence of Ce 3+ substitution on the microstructure and magnetic properties of Sr-ferrite powder was discussed. Results showed that the Ce 3+ ions could completely enter the ferrite lattice when the substitution amount was in the range of x = 0–0.2. The saturation magnetization and intrinsic coercivity of Sr 1−x Ce x Fe 12 O 19 ferrites could be enhanced through Ce 3+ substitution. These enhancements were attributed to the improvements in the magnetic structure and microstructure.
