摘要: Abstract A self-propagating combustion synthesis (SPCS) method, citrate SPCS was used to synthesize Cu0.4Zn0.6Cr0.5SmxFe1.5−xO4 (x=0–0.1) nanosized powders at relatively low temperature. Polyaniline/Cu0.4Zn0.6Cr0.5Sm0.06Fe1.44O4 (CZCS0.06FO) nanocomposites were prepared by in situ polymerization of aniline the presence CZCS0.06FO ferrites. The structures, morphologies, and ferromagnetic properties ferrite characterized powder X-ray diffractometer (XRD), transmission electron microscope (TEM), scanning (SEM), vibrating sample magnetometer (VSM). results indicated that coated effectively polyaniline, which reduced agglomeration particles certain extent, helpful decentralization stabilization nanoparticles. with core-shell structure under applied field exhibited hysteresis loops nature. fit for being as soft magnetic material because their lower coercivity than pure
