• In this work, Ba 0.8 In 0.2 Fe 12−x Ni x O 19 (x = 0.00–2.00) hexaferrites were prepared by the ceramic route, and the effect of ferromagnetic dopant Ni was retrieved on the structure and magnetic properties. Microstructural properties were explored using XRD and SEM. The range of the grain size was between 500 to 2000 nm. In addition to these, micro strain, dislocation density, and porosity were determined. According to the VSM findings, ferromagnetic nickel doping increased the magnetic saturation up to 58.36 emu/g. The coercivity values were observed within a defined range from 5.129 kOe to 5.512 kOe, showing only a slight change. Moreover, the magnetocrystalline anisotropy constant, anisotropy field, and anisotropy parameter were calculated. The results showed that the magnetocrystalline anisotropy constant and anisotropy field both increased up to 0.06308 emu/g.kOe and 1.722 kOe for an increase in doping concentrations and then dropped for x = 2.0. The magnetic moment per formula unit in terms of Bohr magneton was also computed and has an upper limit of 11.603. These results suggest that the synthesized material is a good contender for magnetic applications.
