Abstract

Cationic substitutions and sintering temperature both are crucial variables in modifying the structural and magnetic properties of M-type hexaferrites. The effect of the cationic substitutions on M-type BaFe10−xAl2MgxO19 hexaferrites is examined in the current work. An XRD analysis reveals that Fe2O3 phases are present as an impurity in all of the samples. Firstly, lattice parameters a and c show a decrease, then start increasing. The(Mr/Ms) ratio confines within a specific stable range. Morphology of the samples shows the uniform distribution of the particles throughout all the compositions.The anisotropy field-(Ha) and coercivity-(Hc) show an increase with increasing doping levels. The average grain size (D) grew continuously between 200 and 900 nm as the the doping content of Mg ascended. At a doping content of x = 0.05, the M type BaFe9.95Al2Mg0.05O19 hexaferrites shows the excellent magnetic characteristics having mB = 9.4098µB, Ms = 49.95 emu/g, Hc = 4.98 kOe, and Ha = 1.6kOe. The findings suggest that M-type hexagonal ferrite’s magnetic properties can be significantly enhanced by varying the cationic substitutions.
