Summary: The NiCo2O4@Fe3O4 composites with excellent electromagnetic wave absorption performance were prepared by a low-temperature co-precipitation method. The combination of NiCo2O4 and Fe3O4 increased the specific surface area of the composite material, leading to improved reflection and scattering of electromagnetic waves. The impedance matching between the magnetic and dielectric materials enhanced the absorption loss performance of the electromagnetic waves.
