Temperature Dependent Structural Studies and Magnetic Properties of BaCa₂Fe₁₆O₂₇ Hexaferrites Prepared by Stearic Acid Gel Route in Presence of SDS Surfactant

The preparation of BaCa₂Fe₁₆O₂₇ hexaferrite powders by a stearic acid gel method with SDS surfactant has been investigated at various sintering temperatures. The samples were characterized by X‐ray diffraction, scanning electron microscopy (SEM), TGA, FTIR and vibrating sample magnetometer (VSM). The effect of sintering temperature on properties of BaCa₂Fe₁₆O₂₇ hexaferrites was studied. In presence of sodium dodecyl sulfate (SDS) surfactant, the magnetic parameters, like saturation magnetization, coercivity and remanent magnetization, have been calculated from hysteresis loop.
