“…XRD Patterns of the magnetic powders were in figure 2. The results could be well indexed with JCPDS#43-0002 within hexagonal structure P63/mmc (S.G. = 194) and well matched with the parent compound [25]. As the doping increases, a change in the intensity of the diffraction peak could be observed clearly.…”

Current study describes the structural and magnetic properties of Ba0.9Sm0.1Fe12-xAlxO19 (x=0.0, 0.5, 1.0, 2.0, 3.0) M-type hexaferrites. Conventional ceramic route was implied to prepare all the nominal samples. Morphological analysis suggested the non-presence of secondary phases as well as formation of the hexaferrites material. X-ray Diffraction technique was used for structural analysis from which microstructural parameters are calculated and discussed. Magnetic properties are measured at room temperature. The saturation magnetization (Ms) and coercivity (Hc) values shows a cyclic and converse trend for synthesized samples. Firstly, a decrease in Ms and increase in Hc was observed up to intermediate dopant incorporation, and becomes converse for higher doping levels. The maximum coercivity and minimum magnetization is observed for Ba0.9Sm0.1Fe11Al1O19. The c/a and Mr/Ms ratio suggest the formation of perfect M-type hexaferrites. This work suggests that synthesized material is a good option for magnetic applications e.g., transformer and inductor cores, microwave devices, recording heads, and magnetic shielding.

“…The calculated values of bond lengths and bond angles at Fe sites are within the range of reported values for doped M-type hexaferrite systems. 31,39,45,46 The refined results of the BaM system showed equivalent values for all 6 Fe–O bond lengths at 2a octahedral sites, whereas all Fe–O bond lengths are not equivalent for the rest of the Fe sites. The Ba–O bonds at Ba sites formed two groups with a slight length difference.…”

“…In order to achieve an improvement in the magnetic properties, the M element is replaced with a couple of rareearth ions. At the room temperature, undoped barium hexaferrite exhibits a saturation magnetization of 70 emu/g [66][67]. The replacement of Ba and/or Sr crystallographic sites in the hexaferrite lattice by the rare earth cations results in changing the valence state of Fe 3+ to Fe 2+ which is located on the 2a site.…”

Hexaferrites are composed of irons and many other divalent metal ions in various atomic ratios. They are classified as M, W, X, Y, Z, and U type according to the crystalline structure. They are also used as ferromagnetic compounds. These materials have been utilized as the permanent magnets, magnetic recording media and microwave absorbers due to their superior properties. These materials also have wide application in ferrofluids, sensors, loudspeakers, electric power generation, rotors in small direct current (DC) motors, automotive electronics, ferrite cores, fabrication of inductors, micro electro mechanical systems (MEMS), capacitors, transistors, microwave, and in magneto static and electromagnetic devices. BaFe12O19 has gain focus in recent years due to its large coercivity, high magneto crystalline anisotropy, relatively large saturation magnetization, electrical resistivity, low cost, and ability to resist corrosion. The Present chapter will focus on the effect of substitution on the dielectric and magnetic properties BaFe12O19. Morphology and properties of barium hexaferrites, effect of Co-Ti substitution on magnetic properties of nanocrystalline BaFe12O19 and effect of rare-earth materials substitution on the micro structural and magnetic properties of BaFe12O19 are covered.
