Explored the synthesis of SrFe12O19/NiFe2O4 nanocomposites using Calotropis gigantea flower extract. Different weight ratios revealed variations in crystallite size, magnetic behavior, and dielectric properties. Hard ferrite dominance in 9:1, 8:2, 7:3 ratios, while 5:5 exhibited soft magnetic nature. Coercivity and saturation magnetization decreased with an increase in spinel phase. Mössbauer study provided insights into relative phase percentages. Dielectric analysis unveiled frequency-dependent behavior. The Green synthesis method showcased promise for tuning nanocomposite properties.
