Graphical Abstract:


La-doped Barium-ferrite/Poly-m-toluidine composites with electromagnetic behavior were prepared by in situ polymerization of m-toluidine in the presence of La-doped Barium-ferrite particles. The structures, morphologies and properties of composites were characterized by Fourier transform infrared (FTIR), X-ray diffraction (XRD), transmission electron microscopy (TEM), four-probe conductivity tester and vibrating sample magnetometer (VSM). FTIR and XRD spectra demonstrated that there were interactions between ferrite and poly-m-toluidine (PMT). TEM studies showed that the composites presented the core-shell structure. Under applied magnetic field, nanocomposite exhibited the hysteretic loops of the ferromagnetic behavior. The magnetic parameter saturation magnetization of composites depends on the content of La-doped barium-ferrite particles.
