| Popis: | Mg–Ti substituted barium hexaferrite (BaMg0.6Ti0.6Fe10.8O19) nanoparticles prepared by using steel millscale waste have been investigated towards the structural, magnetic and microwave properties. The samples were prepared using high-energy ball milling technique with the hematite (Fe2O3) as the raw utilized and processed from millscale waste product. The peaks with a single phase hexagonal structure of BaMg0.6Ti0.6Fe10.8O19 are identified at 1000 °C revealed from X-ray diffraction analysis. Higher saturation magnetization, Ms, with high crystallinity was observed in the sample due to the enhancement of superexchange interaction within the sample. The best maximum reflection loss of − 22.59 dB at the frequency and bandwidth of 9.42 GHz and 0.14 GHz was achieved in sample sintered at 1000 °C. |
