Abstract
Samples of Barium Hexaferrite doped with Titanium BaFe12−xTixO19 with (x = 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 Ms, remanence (Mr), the relative ratio (Mr/Ms), and the coercivity (Hc) were calculated. The study showed that the saturation magnetization (Ms) and remanence (Mr) 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 (Hc) 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.

The average crystallite size for all samples was in the range of 27–42 nm
The values of saturation magnetization (Ms) retentivity (Mr ) calculated values decreased with increasing the Ti concentration, and this may result and retentivity (Mr) calculated values decreased with increasing the Ti concentration, and this may from particle size effects
Summary
There are vast numbers of applications based on magnetic materials and as a result of that; our lives have improved They are used in the fabrication of many types of equipment and have a major role in the advancement of technological and industrial products. First discovered in the 1950s, are ceramics made from iron oxides with one or more additional metals chemically added [4,5] These ferrites had been considered very highly valuable electronic materials for many decades. There was an increasing degree of interest in hexaferrites, and it is still growing today. They have been massively produced and became important materials; commercially and technologically used in many electrical systems, such as permanent magnets, magnetic recording and data storage devices [6,7]
