Temperature dependent structural studies and magnetic properties of BaCa₂Fe₁₆O₂₇ hexaferrites prepared by stearic acid gel route in presence of SDS surfactant

Abstract

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.
