The invention relates to a micron-scale succulent porous iron-cobalt alloy and its preparation and application. Through a convenient synthesis strategy of hydrothermal reaction-hydrogen-argon reduction, the micron-scale succulent porous iron-cobalt alloy is successfully constructed. Its stable vortex domain structure can improve the magnetic storage capacity, and the violent motion of the magnetic moment helps to improve the magnetic loss capacity, so that the material has a high complex magnetic permeability. The porous structure increases multiple scattering and optimizes impedance matching. Therefore, compared with the prior art, the succulent iron-cobalt alloy material in the present invention has an effective absorption bandwidth of 5.7GHz, a maximum reflection loss of ‑53.8dB, and exhibits excellent electromagnetic wave loss capability in the frequency range of 2.0‑18.0GHz . |
