Electromagnetic Attenuation of Sm‐Doped Alloys Modified by Interface Exchange Coupling and Magnetocrystalline Stress Anisotropy

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 7, 2025

Abstract The narrow resonance width of magnetic alloys limits their application as wide frequency electromagnetic wave absorbers within the gigahertz range. To address this issue, study proposes engineering homogeneous interfaces and enhancing anisotropy through Sm doping in FeCo alloy, thereby giving rise to a broadened an increased loss. results show that Sm‐doping produces abundant grain boundaries strengthening charge transfer (0.16 ev) moment (0.34 µ B ), which ultimately heightens interfacial exchange coupling coefficient by six times. Furthermore, magnetocrystalline constant rises from 4.1 × 10 5 3.0 10⁶ J m − 3 , stress expands four fold, owing induced 4f electron spin‐orbit lattice distortion. Consequently, natural are elevated 10.4 6.4 GHz, separately. Eventually, with loss angle above 0.5 over 7–14 GHz present ultra‐wide absorption. This work provides new approach homointerface improve absorption alloys.
