SrFe₁₂O₁₉/Ni_0.6Zn_0.4Fe₂O₄ powders were prepared by the one-pot solution combustion method. The effect of calcination temperatures (700°C and 800°C) on phase, structure, microstructure and magnetic properties of SrFe₁₂O₁₉-x Ni_0.6Zn_0.4Fe₂O₄ (x = 0 wt.%, 10 wt.%, 20 wt.% and 30 wt.%) composites were investigated by x-ray diffractometry, scanning electron microscopy and vibrating sample magnetometry techniques. Strontium hexaferrite and spinel ferrite phases were formed through calcination at 800°C together with some α-Fe₂O₃ phase, while spinel ferrite was mainly crystallized at 700°C. The saturation magnetization slightly increased from 38 emu/g to 42 emu/g with the addition of 10 wt.% of Ni_0.6Zn_0.4Fe₂O₄ and then decreased to 36 emu/g at a calcination temperature of 800°C. The microwave absorption measurements in X-band (8–12 GHz) showed a minimum reflection loss of − 14.5 dB at 9.5 GHz for SrFe₁₂O₁₉-10 wt.% Ni_0.6Zn_0.4Fe₂O₄ composite synthesized at 800°C.
