“…Incorporation of Y 3+ (µB=0) ions by Fe 3+ ions decreases the magnetic moment and the difference in ionic radii Y 3+ (0.090 nm) and Fe 3+ (0.064 nm) causes reduction of exchange interactions of Fe 3+ -O 2--Fe 3+ that results in decrement in magnetic parameter. The obtained values of Y 3+ substituted strontium hexaferrite nanomaterial reveal it to be a promising material for the application in longitudinal recording media [19][20][21].…”

Yttrium (Y3+)-substituted strontium hexaferrite nanoparticles with composition SrFe12-x Y x O19 have been synthesized using the sol-gel method. Diverse analytical tools have been applied to characterize the prepared strontium hexaferrite nanoparticles and to analyse the influence of yttrium (Y3+) substitution on the structural and magnetic properties. X-ray diffraction patterns confirm the presence of single phase M-type hexagonal crystalline structure. In fourier-transform infrared spectroscopy, the absorption bands at low wavenumber confirmed the formation of hexagonal ferrites. The vibrating sample magnetometer has been employed to study the magnetic behavior of Y3+ ions substituted strontium hexaferrite. The decrease in saturation magnetization (Ms) and coercivity (Hc) value has been explained on the basis of alteration in magnetic interactions due to the replacement of both Fe3+ ions by the non-magnetic Y3+ ions.

“…With the rapid development and wide application of microwave in gigahertz range for electronic and telecommunication systems such as mobile phone and radar systems, the demand for various kinds of radar absorbing materials (RAM) has increased to reduce electromagnetic interference [1]. Generally, the loss mechanisms of RAM classify as dielectric loss demonstrated by permittivity, and magnetic loss demonstrated by permeability [2].…”

NiCrAlY/Al 2 O 3 coatings were fabricated by low power plasma spraying with two different feedstock powders. The microstructure, phase composition and dielectric properties of the coatings were investigated. The result showed that the particle melting degree and the connection of NiCrAlY in the coatings were closely related to the feedstock characteristics, such as particle size and morphology, which played an important role in the microstructure and dielectric properties. The enhanced complex permittivity of the coating deposited from dried and crushed powder is attributed to interfacial polarization and conductance loss. Compared with the coating prepared from milled and agglomerated powder, the reflection loss of the coating fabricated with dried and crushed powder reaches -20.5 dB at 9.9 GHz and the eligible microwave absorption (below -10 dB) can be obtained in the frequency range 8.7-10.8 GHz.

“…[32][33][34][35] Research into EM wave absorbers began in the 1930s and has the first patent in 1936 from the Netherlands. [36] EM wave absorption materials may considerably increase weapon systems' survivability and penetration capability, reduce EMI from communication and navigation systems, and safeguard human physical security. With the advancement of military stealth technology and the internet of things' EM compatibility technology, EM wave-absorbing coating materials have garnered increasing interest.…”

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.
