In this study, the Ni-P-Fe 3 O 4 composite powders containing about 10% phosphorus were prepared by hydrothermal method. The phase, composition and morphology of the powders were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and transmission electron microscopy (TEM), respectively. The wave absorption properties of the Ni-P-Fe 3 O 4 composite powders were estimated by vector network analyzer (VNA). The results showed that the saturation magnetization and resistivity of the as-obtained Ni-P-Fe 3 O 4 composite powders were significantly reduced, however their dispersion as well as conductivity were improved. The electromagnetic wave absorbed by Ni-P-Fe 3 O 4 composite powders was mainly attributed to the dielectric loss, and the absorption of electromagnetic wave in the low frequency can reach to 90% (the reflection loss is less than -10 dB).
