摘要: Abstract Core–shell-structured LiNi0.5La0.08Fe1.92O4–polyaniline (PANI) nanocomposites with magnetic behavior were synthesized by in situ polymerization of aniline the presence LiNi0.5La0.08Fe1.92O4 nanoparticles. The structure, morphology and properties samples characterized powder X-ray diffraction (XRD), Fourier transform infrared (FTIR), UV–vis absorption, transmission electron microscopy (TEM) vibrating sample magnetometer (VSM) technique. results spectroanalysis indicated that there was interaction between PANI chains ferrite particles. TEM study showed LiNi0.5La0.08Fe1.92O4–PANI presented a core–shell structure core 30–50 nm diameter an amorphous shell 10–20 nm thickness. under applied field exhibited hysteresis loops ferromagnetic nature. saturation magnetization coercivity decreased decreasing content LiNi0.5La0.08Fe1.92O4. mechanism bonding have been discussed.
