摘要: Sol–gel method is used to prepare BaAlFe11O19 hexaferrites, and the morphology of samples has been changed by mixing as obtained with inorganic template agents (KCl, KBr, KI) during annealing process. Fourier transform infrared spectroscopy (FTIR) frequency bands in range 564–588 cm−1 425–442 cm−1 are corresponding formation tetrahedral octahedral clusters metal oxides respectively. X-ray powder studies do not show any peak for sample, however, regular diffraction (XRD) peaks were annealed at 1000°C. Magnetic measurement shows that saturation magnetization (Ms) BaAlFe11O19/KI maximum (24.32 emu/g) BaAlFe11O19/KCl minimum (9.47 emu/g). The coercivity (Hc) values sample KCl (3237 Oe) KI (700 Oe).
