| Summary: | Samples of Barium Hexaferrite doped with Titanium BaFe<sub>12−<i>x</i></sub>Ti<i><sub>x</sub></i>O<sub>19</sub> with (<i>x</i> = 0.0, 0.2, 0.4, 0.6, 0.8, 1.0) were synthesized by the sol−gel auto-combustion technique. The powdered samples were divided into two parts, one sintered at 850 °C and another sintered 1000 °C for 1 h and samples were characterized by different experimental techniques. The XRD patterns confirmed the presence of M-type hexaferrite phase. The sizes of the crystallites were calculated by the Scherer equation, and the sizes were in the range of 27−42 nm. Using the hysteresis loops, the saturation magnetization M<sub>s</sub>, remanence (M<sub>r</sub>), the relative ratio (M<sub>r</sub>/M<sub>s</sub>), and the coercivity (H<sub>c</sub>) were calculated. The study showed that the saturation magnetization (M<sub>s</sub>) and remanence (M<sub>r</sub>) decreased with increasing titanium concentration and were in the range from 44.65−17.17 emu/g and 23.1−7.7 emu/g, respectively. The coercivity (H<sub>c</sub>) ranged between 0.583 and 4.51 (kOe). The magnetic properties of these Barium Hexaferrite doped with Titanium indicated that they could be used in the recording equipment and permanent magnets.
