Lithium ion-substituted hexagonal strontium ferrite (Sr1−xLi2xFe12O19, where x = 0.1, 0.2, and 0.3) powders have been successfully fabricated using tartrate precursor route. The impact of Li+ content, as well annealing temperature on the phase evolution, microstructure, magnetic performance, was monitored by X-ray diffraction profile, scanning electron microscopy, vibrating sample magnetometer....
