“…The S-0h shows a higher value of ε' and ε", but the S-6h exhibits a lower value of ε' and ε". However, there is a resonance peak value of about 5.7 at 15.8 GHz for the S-0h, which is similar to the value of ε" for NiMnGa alloys [4]. The resonance peak can be attributed to the interfacial polarization between the γ phase and L2 1 phase in S-0h.…”

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.

“…The ideal MAMs possess the characters of being strong, wide, light, and thin. Due to microwave-absorbing properties being co-determined by attenuation ability and impedance matching, numerous efforts have modified micromorphology, components, and microstructures to balance the attenuation ability and impedance matching [2][3][4][5].…”

“…The ideal MAMs should not only be strong, wide, light, and thin but also meet the technical requirements of environmental friendliness, low-cost approaches, and plentiful availability [ 2 ]. Carbon-based materials [ 1 , 3 , 4 , 5 ], ceramics [ 6 , 7 , 8 , 9 , 10 ], and magnetic alloy powders [ 3 , 11 , 12 , 13 , 14 ] represent typical potential microwave absorption materials.…”

Carbon-based composites have been proven to be strong candidates for microwave absorbers in recent years. However, as an important member, magnetic hard carbon (HC)-based composites have rarely been studied in the field of microwave absorption. In this study, HC embedded with FeSiAl (FeSiAl@HC) was synthesized by pyrolyzing a mixture of FeSiAl flakes and phenolic resin (PR). The as-synthesized HC-FeSiAl exhibited a layered structure, and the detailed microstructures were modified by changing the mass ratio of FeSiAl flakes and PR. Thus, the as-synthesized HC-FeSiAl exhibited tunable magnetic properties, wealthy functional groups, excellent thermal stability, and enhanced microwave absorption properties. The optimal minimum reflection loss is lower up to −36.1 dB, and the effective absorption bandwidth is wider up to 11.7 GHz. These results indicated that HC-FeSiAl should be a strong candidate for practical applications of microwave absorption, which may provide new insight into the synthesis of magnetic HC-based composites.
