The BaFe 12 O 19 /multiwall carbon nanotubes/poly(3‐methyl‐thiophene) (BaFe 12 O 19 /MCNTs/P(3MT)) composites were synthesized through an in situ chemical polymerization of 3‐methyl‐thiophene (3MT) in the presence of BaFe 12 O 19 /MCNTs composite powders. The BaFe 12 O 19 /MCNTs/P(3MT) composites were characterized by the fourier transform infrared spectrometry (FTIR) and X‐ray diffraction (XRD). The morphologies of the composites were observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The electric conductive properties were tested by a four‐probe conductivity tester and the magnetic properties were measured by vibrating sample magnetometer (VSM). The electromagnetic performance tests showed that when the mass ratio of BaFe 12 O 19 to MCNTs was 0.4, and the BaFe 12 O 19 /MCNTs to P(3MT) was 0.15, the conductivity, saturation magnetization ( M s ) and residual magnetization ( M r ) of the BaFe 12 O 19 /MCNTs/P(3MT) composites achieved 166.740 S/m, 29.884 emu/g, and 17.581 emu/g, respectively.
