“…σ ac = ωε 0 ε´ = ωε 0 εtanδ = 2πf tanδ (13) This relationship establishes that ac conductivity (σ ac ) rises as frequency rises. We can calculate the slope (n) by plotting logσac vs logω as a function of Manganese-ytterbium concentration on a graph.…”

“…Y-type hexaferrites with planar magnetic anisotropy have a larger magnetic permeability in the GHz frequency range than other hexagonal ferrites having uniaxial magnetic anisotropy, which is interesting to many researchers [7][8][9]. Hexaferrites are classi ed into different types based on their chemical composition, such as M-, Y-, Z-, X-, U-, and W-type hexagonal ferrites [10][11][12][13]. The Y-type hexagonal ferrites' crystalline structure was described as an alternating stacking of the S and T blocks along the caxis with space group R-3m [14][15][16].…”

This study aimed to determine the effect of Mn2+ and Yb3+ ions substitution on the structural, dielectric, morphological, and magnetic properties of CaBaCo2 − xMnxYbyFe12−yO22 where x = 0.00-0.1 and y = 0.00-0.01 Y-type hexagonal ferrites prepared by sol-gel auto combustion. For 6 hours, samples were calcined at 1050 degrees Celsius. X-ray diffraction (XRD) analysis was used to study the formation phase of Y-type hexaferrites. The calculated structural auxiliary parameters, such as lattice constants (a and c), cell volume (Vcell), X-ray density (dx), bulk density (db), and porosity (P), were found to be within the following ranges: a = 5.891 to 5.9Å, c = .43.466 to 43.543Å, Vcell 1310.53 to 1312.26Å3, dx = 5.01 to 5.05(g/cm− 1) db = 2.622 to 3.032 (g/cm− 1)and P = 39.969 to 47.665%. The location of the ions, including their respective bonds, inside the structure of the lattice matrix, was revealed by Fourier-transform infrared spectroscopy (FTIR). SEM pictures confirmed the plate-like shape of the particles, confirming the XRD findings. In the dielectric analysis, the typical dielectric response of ferrites was observed. Grain contribution is low when compared to grain boundaries contribution The generated Y-type hexaferrites samples' multidomain magnetic nature resulted in domain wall displacement, which affects the coercivity values. A vibrating sample magnetometer was used to investigate magnetic characteristics (VSM). The saturation magnetization (Ms), Retentivity (Mr), and coercivity (Hc) of the material were found to be 4.11 to 2.21 emu/g, 2.33 to 1.22emu/g, and 1776.78 to 2283,51Oe, respectively. These powders can be used as pre-eminent contender materials for perpendicular recording media (PMR) applications. Corresponding Author’s E-mail: hmkhan@iub.edu.pk

With the fast growth of wireless communication technology in high‐frequency ranges, electromagnetic (EM) interference has become a growing concern that has drawn international attention. The development of materials that can absorb EM radiation is a crucial solution. This review provides a detailed overview of ferrites, specifically hexagonal ferrites and their composites for microwave (MW) absorption. It examines hexagonal ferrite classifications based on the stacking order of their fundamental blocks and their synthesis methods and strategies for improving their magnetic properties. On the other hand, this review included a detailed examination of hexagonal ferrites–conducting polymer, hexagonal ferrites–2D materials, and hexagonal ferrite–other nanomaterials composites for MW absorption applications. Enhancing MW absorption in hexagonal ferrites‐based microwave absorption materials (MAMs) regulates their EM characteristics, improves impedance matching, and creates a diversity of loss mechanisms. In addition, the limitations, challenges, and opportunities of hexagonal ferrites‐based MAMs are discussed, which will be helpful to those working in related areas. As a general application potential, it is worth mentioning that, as a result of recent promising findings in the synthesis of hexagonal ferrites‐based composites, hexaferrite‐based composites are suitable devices in the area of microwave absorption.

“…Ferrites with the magnetoplumbite structure (with the space group P6 3 /mmc) have been successfully used for a long time in the manufacturing of high-frequency transformers, fabricating of microwave electronic devices, and manufacturing of magnetic memory devices. They are also used in the manufacturing of functional sensors, as well as for the production of plastoferrites, magnetic fluids, permanent magnets, and multiferroics [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. All these are possible due to the unique structural and magnetic properties of ferrites with the magnetoplumbite structure, as well as their mechanical, chemical and thermal resistance.…”

The purpose of this study is to obtain high-entropy oxides with the magnetoplumbite structure, in which the Pb cation is used as a divalent metal cation. The synthesis conditions were optimized, and a technique was developed to avoid the evaporation of lead oxide. For the first time, single-phase samples of high-entropy oxides with the magnetoplumbite structure were obtained, its chemical composition is reflected by the formula PbFe 2.4 X 2.4 Y 2.4 Ga 2.4 In 2.4 O 19 . The particle size of the high-entropy phase is about 100 nm, which makes it promising for a number of applications. The effect of preliminary grinding of the initial components on the results of synthesis was studied. A synthesis mechanism is proposed. The results pave the way to synthesis and study of the properties of a new large subgroup of high-entropy oxides with the magnetoplumbite structure, which expands the possibilities of controlling the properties of ceramic magnetic materials.
