BaNdFeO 4 revisited: true phase composition, magnetic structure evolution, and broadband microwave absorption in an intrinsic self-composite

Year: 2026

Type: article

Abstract: = (1/2, 0, 0). The intrinsic coexistence of these structurally and magnetically distinct phases produces an interface-rich and defect-prone microstructure that promotes dielectric-dominant broadband microwave absorption. Reflection-loss analysis reveals thickness-tunable absorption governed by effective impedance matching and quarter-wavelength interference, yielding a maximum effective absorption bandwidth of approximately 5.3 GHz at a thickness of ∼5.0 mm. These findings underscore the potential of this Ba-Nd-Fe-O intrinsic self-composite as a promising chemically stable oxide for broadband electromagnetic wave attenuation.
