چکیده انگلیسی
SrFe12O19/Ni0.6Zn0.4Fe2O4 composites were synthesized by one-pot solution combustion method. The effects of NiZn ferrite content on phase, structure, microstructure and magnetic properties of composites were investigated by X-ray diffractometry, infrared spectroscopy, electron microscopy and vibrating sample magnetometry techniques. Strontium hexaferrite and NiZn ferrite phases were well crystallized following calcination at 900â¯Â°C without any impurities being formed. The composites were composed of platelet-like SrFe12O19 particles being mixed with quasi-spherical NiZn ferrite particles. The composites containing 10â¯wt% Ni0.6Zn0.4Fe2O4 exhibited a single magnetization curve with maximum saturation magnetization of 56â¯emu/g, as a confirmation of exchange coupling, while other composites had “bee waist” type hysteresis loop. The coercivity of composites decreased from 5143 to 1778â¯Oe with addition of NiZn ferrite phase. The microwave absorption measurements in X-band (8-12â¯GHz) showed a maximum absorption of â23.5â¯dB at 9.9â¯GHz for SrFe12O19-10â¯wt% Ni0.6Zn0.4Fe2O4 composite in comparison with the other composites.
