Impact of Ferromagnetic Ni Substitution on Structural and Magnetic Parameters of Ba0.8In0.2Fe12−xNixO19 (x = 0.00–2.00) Hexaferrites

Effect of ferromagnetic cobalt on characteristics of coercive Aluminium substituted BaFe11.5Al0.5O19 hexaferrites

“…The model proposes that the ions' spins in these positions are not aligned parallel to the c-axis [61]. This behavior of M S developed as a result of a rise in the hyperfine-fields at the 12k and 2b sub-lattices sites or a rise in the Fe 3+ -O-Fe 3+ superexchange contacts, as seen in earlier studies, as well as spin canting, which was often brought on by rare earth metal ions [10]. It is seen that coercivity H C rises remarkably.…”

“…Cell refinement analysis of the synthesized samples of M-type BaFe 11.5−x Al 0.5 Co x O 19 (x = 0.00, 0.5, 1.0, 1.5, and 2.0) hexaferrites nanoparticles was performed by Celref software [10,45,46]. Lattice parameters of all the produced samples were listed in table 1.…”

“…They possess good electrical and chemical stability, corrosion resistance and have hexagonal regularity [7]. These properties make M-type hexaferrites attractive in numerous magnetic devices, such as permanent magnets, micro-wave devices, and magnetic recording media [8][9][10]. They are crucial in the enterprise of micro-wave instruments (such as phase shifters, circulators, and filters), biomedical applications, and chemical sensing [11][12][13].…”

Microstructural, morphological and magnetic behaviour of Al3+ replaced BaFe11.5Co0.5O19 hexaferrites synthesized via sol-gel auto combustion route

“…There are not any noticeable secondary peaks in any of the XRD graphs, and they all match the ICSD card No. 01-084-0757 and JCPDS card #43-0002 exactly as described by the structural analysis and refinement process [39,40]. The Retvield refinement for the synthesised samples was performed using Fullprof software and fitted profiles are shown in figure 3.…”

“…Moreover, the size of crystallites is determined by the Debye-Scherrer equation. The microstructural variables such as porosity (P), x-ray density-(d x ), bulk density-(d b ), and dislocation density (δ) were determined by using the formulas described in the literature [40]. Strains (ε) and Dislocation density (δ) are important to find out whether there were any empty spaces in the material.…”
