The effect of agarose agent on the structural, magnetic and optical properties of barium hexaferrite nano-particles synthesized by sol-gel auto-combustion method

Influence of Gd and Ni doping on the structural, morphological, and magnetic properties of M-type calcium hexaferrite

“…The potential uses of hexaferrite materials are in electronic gadgets, magnetic recording media, microwave absorbers, data storage, electric motors, etc. 1–7 Hexaferrites are widely applicable due to their specific properties like high saturation magnetization, corrosion resistance, high coercivity, and unique chemical stability and their significant magneto crystalline anisotropy constant is beneficial in high-frequency devices. 8–11 According to structural differences, ferrites have been categorized into four primary families: spinel, orthoferrite, garnet, and hexagonal, 12,13 in which hexagonal ferrites are further classified into six categories based on the chemical structures such as X-type (B 2 Me 2 Fe 28 O 46 ), Y-type (B 2 Me 2 Fe 12 O 22 ), Z-type (B 3 Me 2 Fe 24 O 41 ), M-type (BFe 12 O 19 ), W-type (Bme 2 Fe 16 O 27 ), and U-type (B 4 Me 2 Fe 36 O 60 ), where B represents a bivalent cation such as Ba 2+ , Sr 2+ , Pb 2+ , Cd 2+ , and Ca 2+ and Me represents the bivalent transition metals.…”
