Abstract
The synthesis and characterization of Ba0.6Sr0.4Fe12-xTixO19 system (x = 0, 1, 2, 3) have successfully performed by mechanical milling through solid state method. Stoichiometric quantities of BaCO3, SrCO3, Fe2O3, and TiO2 were mixed. The mixture were first milled for 48 h and sintered at 1000 °C for 5 hrs. The refinement of x-ray diffraction shows that a single phase material with a hexagonal structure and lattice parameters appears to increase with increasing Ti doping. The mechanical milling resulted in powders of all samples with mean size of 90 nm. Results of hysteresis curve shows that the samples are ferromagnetic and have low coercivity after Ti doping. Results of VNA evaluation show that the sample after Ti doping has absorption peaks with high reflection loss values at frequency ∼ 11 GHz. We concluded that this study has been successfully known effect of Ti addition on the microwave absorbing behavior of Ba0.6Sr0.4Fe12-xTixO19system at X-band frequencies.
