摘要：
In this work, SrFe12O19/TiO2 nanocomposites have been synthesized by a sol-gel method. The pure SrFe12O19/TiO2 nanocomposites were obtained by hydrolysis of titanium tetraisopropoxide at pH = 3.5 with a post-calcination process at 500∘C. The magnetic results showed that the saturation magnetization and coercivity decreased with increasing of TiO2 content. Concerning the microwave absorption measurements in the microwave frequency range of 8–12 GHz (X-band), the SrFe12O19-30 wt% TiO2 nanocomposite exhibited the best absorption of −45 dB at 11.2 GHz with an absorption bandwidth of more than 1.5 GHz.
