“…The values of Zin/Z0 from the S-6h approach to 1 across a wider frequency range. The value of Zin/Z0 close to 1 indicates the ideal impedance matching behavior, which is the efficient complementarity between the relative permittivity and permeability [37]. As shown in Figure 5c, the dielectric loss tangent tanδε, and in Figure 5d the magnetic loss tangent tanδμ of three samples, the S-6h exhibits the lowest tanδe and highest tanδμ.…”

Microwave absorption performance of metal alloys are highly dependent on their phase structures. However, the phase control of Ni–Mn-based alloys to achieve effective microwave absorption properties has been rarely reported. In this work, Ni43Co7Mn39Sn11 alloy flakes were fabricated by balling milling method, and the contents of γ phase in the flakes were tuned by the subsequent heat treatment process. The as-fabricated Ni43Co7Mn39Sn11 alloy flakes exhibited excellent tunable microwave absorption by control of their phase structures. The optimal reflection loss was lower, up to −56.4 dB at 8.8 GHz, and was achieved at a single thickness of 2.0 mm. This can be attributed to the optimal structure of Ni43Co7Mn39Sn11 alloy flakes by phase control, and thus achieving improved attenuation property and impedance matching. This study proved Ni43Co7Mn39Sn11 alloy flakes should be a promising microwave absorption material. It is also demonstrated that phase control is an effected strategy for optimal microwave absorption properties of metal alloys and may have some reference value for related studies.

“…Aurivillius BFTO-n can present large dielectric, FE, and FM behaviors and electromagnetic interaction, thus they are likely to be a new type of microwave materials with excellent microwave absorption. Liu et al [202] reported that La-modified La x Bi 5−x Fe 0.5 Co 0.5 Ti 3 O 15 materials have a microwave absorption. Specifically, the specimen with x = 0.75 delivered a minimum RL of −15.8 dB at a small thickness of 1.8 mm and a broadened absorption bandwidth (≤−10 dB) of 3.0 GHz (9.5-12.5 GHz).…”

Driven by potentially photo-electro-magnetic functionality, Bi-containing Aurivillius-type oxides of binary Bi4Ti3O12-BiFeO3 system with a general formula of Bin+1Fen−3Ti3O3n+3, typically in a naturally layered perovskite-related structure, have attracted increasing research interest, especially in the last twenty years. Benefiting from highly structural tolerance and simultaneous electric dipole and magnetic ordering at room temperature, these Aurivillius-phase oxides as potentially single-phase and room-temperature multiferroic materials can accommodate many different cations and exhibit a rich spectrum of properties. In this review, firstly, we discussed the characteristics of Aurivillius-phase layered structure and recent progress in the field of synthesis of such materials with various architectures. Secondly, we summarized recent strategies to improve ferroelectric and magnetic properties, consisting of chemical modification, interface engineering, oxyhalide derivatives and morphology controlling. Thirdly, we highlighted some research hotspots on magnetoelectric effect, catalytic activity, microwave absorption, and photovoltaic effect for promising applications. Finally, we provided an updated overview on the understanding and also highlighting of the existing issues that hinder further development of the multifunctional Bin+1Fen−3Ti3O3n+3 materials.
