Magnetic materials with high coercive fields, often called permanent magnets, have a wide industrial application ranging from loudspeakers to motors, and sensors. In particular, Strontium hexaferrite SrFe12O19 and Barium hexaferrite BaFe12O19 have received considerable attention trying to improve their magnetic properties because of their low price per unit of stored energy, which allows large scale production. Other factors such as high Curie temperature, excellent chemical stability, and light weight are associated with them. Many studies have focused on replacing Strontium (Sr) or Iron (Fe) atoms with magnetic and non-magnetic atoms to improve magnetic properties of these ferrites. The studies on Rare-Earth (RE) substituted SrFe12O19 are abound. However studies on non-magnetic ion substitution on SrFe12O19 are limited. Herein we present a study on the synthesis and characterization of Aluminium (Al) and RE doped SrFe12O19.
