The poly(3-octyl-thiophene)/BaFe11.92(LaNd)(0.04)O-19-titanium dioxide/multiwalled carbon nanotubes (P(3OT)/BF-TD/MCNTs) nanocomposites were synthesized through in situ chemical polymerization of 3-octyl-thiophene in the presence of the BF-TD nanocomposites and MCNTs. Nanocomposites were characterized by thermogravimetry (TG), Fourier transform infrared (FT-IR), X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), vibrating sample magnetometer (VSM). TG, FT-IR and XRD images indicated the formation of P(3OT)/BF-TD/MCNTs nanocomposites. SEM and TEM observations showed the particles size of the BF-TD nanocomposites was less than 50 nm and lots of MCNTs were absorbed by BF-TD nanocomposites. Under applied magnetic field, the nanocomposites exhibited the ferromagnetic behavior. The saturation magnetization, remanent magnetization and coercivity of nanocomposites varied with the content of Ba(LaNd)(0.09)Fe11.92O19 particles. A scheme for the formation of the nanocomposites was proposed. When the BF and TD mass ratio was 6:5, P(3OT)/BF-TD/MCNTs nanocomposites possessed the best magnetic parameter.
