Magnetic composite containing polyaniline (PANI)‐coated LiNi 0.5 Gd 0.08 Fe 1.92 O 4 was synthesized by in situ polymerization of aniline on the surface of LiNi 0.5 Gd 0.08 Fe 1.92 O 4 ferrite particles. The obtained samples were characterized by powder X‐ray diffraction, Fourier transform infrared spectra, UV–visible absorption spectra, thermogravimetric analysis, transmission electron microscopy (TEM), and vibrating sample magnetometer. The results of spectroanalysis indicated that there was interaction between PANI chains and ferrite particles. TEM study showed that composite presented the core–shell structure. The composite under applied magnetic field exhibited the clear hysteretic behavior at room temperature. The bonding mechanism in the composite had been discussed. © 2007 Wiley Periodicals, Inc.
