“…Moreover, some studies have focused on the introduction of rare-earth elements (e.g. Pr, Nd, La, and Ce), so that the EM properties of Nibased alloys could be finely regulated by their unique electronic structure [81][82][83][84]. However, in terms of current results, the introduction of rare-earth elements has not yet significantly upgraded the microwave absorption performance of Ni-based alloys.…”

Microwave absorption is emerging as a sustainable pathway through which to alleviate various problems induced by increasingly serious electromagnetic (EM) pollution and interference. As a platform for the conversion of EM energy, microwave-absorbing materials (MAMs) have received widespread attention and have been intensively studied in the past two decades. Among all kinds of materials with characteristic EM functions, the metal Ni has always been regarded as one of the most promising candidates, due to its good magnetic loss, compatible dielectric loss, and high Snoek's limit, as well as its easy production and abundant global reserves. However, it is still difficult for raw Ni particles to realize desirable absorption efficiency, and thus a lot of research has been carried out in the areas of microstructure optimization, alloying, and the composite design of Ni particles to significantly upgrade their microwave absorption performance. This review provides a comprehensive introduction to recent advancements in various high-performance Ni-related MAMs, including hierarchical Ni particles, Ni-based alloy particles, Ni-related composites with metal oxides/sulfides/conductive polymers/various carbon materials, and multicomponent Ni-related composites. Thanks to the synergistic effects between different components and elaborate microstructure designs, these Ni-related MAMs can produce a remarkable improvement in microwave absorption performance. Moreover, the challenges and prospects are also discussed in order to provide some new insights into further research in the field of Ni-related MAMs.

Fe3GeTe2 provides an ideal system for the study of itinerant ferromagnetism. However, the Curie temperature (Tc) below room temperature limits its further in‐depth research and wide applications. Here, the Tc of 224 K for Fe3GeTe2 is greatly increased to 496 K for Fe3GeTe2/FeTe2/Fe3Ge by temperature‐induced self‐decomposition doping, contributing to improve the electromagnetic response for enhancing the absorption strength and bandwidth and boosting application potentials at higher temperatures. Then, to achieve the multispectral compatible strong absorption, room temperature ferromagnetic dielectric graphene@Fe3GeTe2/FeTe2/Fe3Ge absorber with 3D porous network structure is prepared by synergistic self‐assembly. It has high Tc of 443 K with strong electromagnetic synergistic loss, achieving reflection loss of −61 dB at 12.6 GHz. Moreover, its absorption loss in the terahertz band (0.1–1.6 THz) is 76 dB, and the average loss is greater than 50.4 dB. Furthermore, the absorber is very potential as stealth skin to efficiently reduce satellite RCS with a multi‐angle and multi‐band manner in the gigahertz and terahertz bands, thus achieving the purpose of stealth. Compared with the reported conventional absorbers, the absorber has a multispectral compatible strong absorption performance covering gigahertz and terahertz bands, thus very promising for electromagnetic protection of electromagnetic communication and space vehicles.
