“…The pseudo‐single domain appears due to the magnetostatic couplings between the magnetic ions. [ 49 ] The calculated values of squareness ratio for each sample are listed in the Table 6. The values are range from 0.404 to 0.569, this range shows that the prepared samples show the multi‐domain magnetic structure at the concentration (x = 0,0.02,0.06, y = 0,0.1,0.3) and gradually tends towards the pseudo‐single domain structure at concentration (x = 0.1, y = 0.5).…”

The main theme of this work is to synthesize and investigate different properties of Pr3+‐Cu2+ substituted X‐type hexaferrite Sr2‐xPrxCo2Fe28‐yCuyO46 with concentration (x = 0, 0.02, 0.06, 0.1 and y = 0, 0.1, 0.3, 0.5) by adopting the sol–gel method. The XRD patterns show the single phase for all the samples. The Pr3+‐Cu2+ substitution in pure X‐type hexaferrites changes the structural parameters. The increment in dielectric properties with Pr3+‐Cu2+ substitution is observed and the patterns show anomalous dielectric behavior. The FTIR analysis also confirms the single phase for the prepared materials. The magnetic properties of the material are enhanced with additives. The difference in saturation magnetization, coercivity, and remanence is observed on the basis of allocated cations onto the different lattice sites. The linear increase in saturation magnetization, remanence, and coercivity make them useful as permanent magnets. The thermal analysis is carried out to know the sintering temperature at which the single X‐type phase can be attained. The material exhibits the minimum value of reflection loss (microwave absorption) at higher frequencies that make this material useful to act as microwave absorbing material (MAM) for super high frequency (SHF) devices.

“…[105,106] Because of its outstanding magnetic and electrical properties, the X-type is suitable for electrical equipment, motors, and magnetic recording media. [107] The substitution of cations and the condition of the synthetic method determine the different electrical, magnetic, and mechanical properties. [108] Ye et al [109] synthesized X type hexaferrite by solid-state reaction at 1240 and 1300 °C for 5 h. They obtained a single crystalline phase, and the saturation magnetization for the entire samples decreased with temperature.…”

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.

“…Hexaferrites (M, W, X, U, Y, Z types) have a signi cant request in daily life during the last decades. Among them, Strontium-based M-type hexaferrite ( MFe 12 O 19 ) is a paramount demand for different industrial, military, and home equipment applications [1][2].In this context, SrFe 12 O 19 emerges exemplary features involving relatively large saturation magnetization, high coercive force, outstanding Curie temperature, pronounced magneto-crystalline anisotropy, excellent chemical and thermal stability, high dielectric constant, low conductive losses, corrosion resistance, non-toxicity, andsimple accessibility [3][4][5][6].

Lithium ion substituted hexagonal strontium ferrite (Sr 1-x Li 2x Fe 12 O 19, where x= 0.1, 0.2, and 0.3) powders have been felicitously fabricated using tartrate precursor scheme. The impact of the Li + content, as well as the annealing temperature on the phase evolution, microstructure and magnetic performance, was commanded by X-ray diffraction pro le (XRD), scanning electron microscopy (SEM), and vibrating sample magnetometer (VSM). Single phase hexagonal ferrite was consummated at a Li + ratio of 0.2 and different annealing temperatures, from 1000 to 1200 o C for 2h. An impurity α-Fe 2 O 3 phase was noted at a high Li + concentration of 0.4 and 0.6 at all temperatures. The crystallo-aspects characteristics were altered with Li + content and annealing temperature. The microstructure of pure hexagonal ferrite sample visualized platelet like structure. A ne spherical shape displayed with platelet shape by enhancing the Li + content up to 0.4 and 0.6. EDX analysis emphasized Fe, Sr, O, and Li atoms spread between the plate and spherical shapes. Good saturation magnetization (Ms=60.88 emu/g) was realized for Li + content of 0.2 as the results of increasing the thickness of the nanoplatelet structure.
