Magnetic Domain Configuration Evolution
Micromagnetic simulations and off-axis electron holography visualize this evolution, revealing the formation of a novel coupled vortex-domain state that significantly enhances low-frequency permeability, breaking the Snoek limit.
Enhanced Electromagnetic Wave Absorption
The tailored magnetic domain configurations, coupled with the introduction of a built-in electric field, lead to significantly enhanced low-frequency electromagnetic wave absorption (EMWA) properties. NF@NCA-3 achieved an effective absorption bandwidth (EAB) of 3.68 GHz, covering nearly the entire C-band (4-8 GHz).
Performance Comparison of NF@NCA Composites
| Sample | RLmin (dB) | Thickness (mm) | EABmax (GHz) | Key Advantage |
|---|---|---|---|---|
| NF@NCA-1 | -14.24 | 3.80 | 2.4 | Baseline |
| NF@NCA-2 | -57.41 | 4.00 | 3.2 | Strong RLmin |
| NF@NCA-3 | -31.02 | 3.74 | 3.68 | Max EAB (C-band) |
| NF@NCA-4 | -63.57 | 5.50 | 3.36 | Highest RLmin |
This exceptional magnetic interaction, combined with optimized impedance matching and high attenuation constants, ensures efficient penetration and dissipation of EMWs, addressing challenges like the skin effect in metallic MNPs.
Multifunctional Performance & Robust Metamaterials
Beyond EMWA, the NF@NCA composites demonstrate additional critical functionalities. They offer significant radar stealth capabilities, validated by RCS simulations showing up to 32.68 dB m² reduction, and excellent thermal insulation performance, with a temperature difference exceeding 63°C, making them suitable for extreme temperature conditions.
