Abstract
La/Sm-doped strontium-ferrite/poly-m-toluidine) (PMT) composites were synthesized by in-situ chemical polymerization of m-toluidine in the presence of La/Sm-doped strontium-ferrite particles. Structural, morphological and electro-magnetic properties of nanocomposites were performed by Fourier transform infrared (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM), four-probe conductivity tester and vibrating sample magnetometer (VSM). The results of XRD indicated that La3+ and Sm3+ had entered into the lattice of strontium ferrite. FTIR spectra demonstrated that there were interactions between ferrite particles and PMT. SEM studies showed that the composites presented the core-shell structure. Under applied magnetic field, nanocomposite exhibited the hystereric loops of the ferromagnetic behavior. The saturation magnetization and coercivity of nanocomposites varied with the content of (LaSm)0.06SrFe11.88O19particles.
