“…Because of their extraordinary characteristics, M type hexaferrites are used in a wide range of applications including magnetic recording media, hexaferrite-based magnetic tapes and disks etc. Furthermore, they are suitable for use in the microwave heating, catalysis, and automotive industries due to their great temperature stability [9][10][11]. M type hexaferrites have also demonstrated promise in medicine, where they may be used in drug administration, hyperthermia treatment, and magnetic resonance imaging.…”

In this work, polycrystalline BaFe11.5-xAlxCo0.5O19 (0≤x≤2) hexaferrite samples were synthesised by means of the sol-gel technique. Thereafter, the magnetic and structural properties are thoroughly examined. Cell refinement and XRD examination verified a magnetoplumbite hexaferrite arrangement with a space group of P63/mmc for each sample. The parameters 'a' and 'c' in the lattice fall in value from 5.885 Å to 5.875 Å and from 23.117 Å to 23.049 Å, respectively. Both the average crystallite size and the unit cell volume exhibit a declining trend as the doping level increases. For M-type hexaferrites, the optimal range of c/a values is determined to be 3.923-3.928. The refining process quality was confirmed by the fit good-ness (χ2) values, which fall within the range of 1.079-1.094. X-ray density (dx) and bulk density (db) decline with rising doping contents until x=1.5 doping content, at which point they exhibit an increasing trend. The results showed that as the doping amount increased, the saturation and remanence magnetizations decreased. Coercivity and magnetocrystalline anisotropy are rising together. Both the anisotropy field (Ha) and the anisotropy parameter (B) exhibit a rising trend with doping content. Coercivity of 5.896 kOe, anisotropic applied field of 1.84 kOe, saturation magnetization of 42.68 emu/g, remanence magnetization of 24.414 (emu/g), and magnetic moment per formula unit-(mB) of 11.19µB are the best magnetic properties obtained for the BaFe10Al1.5Co0.5O19 sample.

This research article reveals the effect of Dy +3 substitution on ?-ferrites KFe 11-x Dy x O 17 with composition (x=0.00, 0.25, 0.50, 0.75 and 1.0). The samples were synthesized by sol-gel auto- combustion method, sintered at 950 o C temperature. The XRD patterns confirmed the single phase of the synthesized samples. The crystallite size varied in the range of 21.49 nm to 25.24 nm for all samples. The polarization verses electric field (P-E) loops indicated the loosy behavior in all samples. The lossy behavior of the samples was seemed to be increased up to x=0.5 and then decreased. The theoretical expression was used to fit an upper branch of P-E loops. FT-IR spectra showed absorption bands at different wavenumbers due to M-O-M stretching vibrations, H-O-H stretching, and C-O-C stretching vibrations, which also confirmed the formation of the single-phase in the samples. Electrochemical measurements of synthesized nano ferrites were carried out by using cyclic voltammetry in a 3.0 M KOH solution. Electrochemical impedance spectroscopy (EIS) has been described by Nyquist plots.
