Effect of Substitution on the Electric and Magnetic Properties of SrFe12O19 Hexa Hard Ferrites

The hexagonal ferrites, also known as hexaferrites, have stimulated interest subsequent to their finding in the 1950s, which is steadily growing today. Both commercially and technologically, these materials grown importance. In addition employment permanent magnets, they are commonly used “magnetic recording data storage materials, well components electrical systems, notably those that activates at microwave/GHz frequency range”. goal of presented study offer new ideas for development magnetic samples Strontium hexaferrite SrFe12O19 (SrM) suited specific applications, explain influence rare-earth (RE) substitution on properties SrM.
