Abstract: Nanocomposites of PAn-DBSA/γ-Fe2O3with electrical and ferromagnetic behavior(σ= 2.18×10-3-5.00×10-5S/cm, Ms=3.7-16.6m2·A/kg, Hc=8805.2-9133.1A/m) were prepared by a chemical modification-redoping method in a neutral medium. The products were characterized by TEM, XRD, UV-Vis, four-probe method, and magnetometer. The results indicate that the electrical and magnetic properties of the nanocomposites strongly depend on γ-Fe2O3content. With the increase of γ-Fe2O3content, the electrical conductivity is decreased and saturation magnetization is increased.
