The composites of polyaniline/polyacrylamide/Zn0.4Ni0.5Cu0.1Fe2O4 (PANI/PAM/ZNCFO) were prepared via solution polymerization. The structure, component, morphology and magnetic property of the composites were characterized by X-ray diffractometry (XRD), Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM) and vibrating sample magnetometry (VSM), respectively. The tangent value of magnetic loss angle and dielectric loss angle of the composites were measured by an impedance/material analyser with the frequecy in the range of 1 MHz~1 GHz. The results revealed that there were some interactions between the magnetic particles and the polymers in the composites, and the composites had good capability of electromagnetic loss in the range of 1 MHz~1 GHz.
