Coordination Thermodynamic Control of Magnetic Domain Configuration Evolution toward Low‑Frequency Electromagnetic Attenuation (IMAGE)
Caption
- A periodic coordination thermodynamical strategy is proposed to modulate magnetic domain configurations, which is visualized by micromagnetic simulation and off-axis electron holography.
- The built-in electric field at the Fe-injected Ni/N-doped carbon aerogel (NF/NCA) interface, together with magnetic coupling, significantly enhances low-frequency electromagnetic wave absorption properties, as validated by an equivalent circuit model.
- NF@NCA composites offer additional radar stealth and thermal insulation performances, suitable for extreme temperature conditions; and a "robust" gradient metamaterial achieves 2–40 GHz absorption.
