摘要: Magnetic nanocomposites containing polyaniline (PANI)-coated La-substituted LiNi ferrite (LiNi0.5La0.02Fe1.98O4) were synthesized by in situ polymerization aqueous solution of hydrochloric acid. The exhibited the magnetic hysteresis nature under applied field. saturation magnetization (MS) and coercivity (HC) varied with content. obtained characterized X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning (SEM), Fourier transform infrared spectroscopy (FT-IR), UV-Visible vibrating sample magnetometer (VSM). TEM SEM studies showed that present core-shell structure. results XRD patterns, FT-IR spectra indicated formation PANI-LiNi0.5La0.02Fe1.98O4 interaction existed between PANI backbone particles nanocomposites. bonding mechanism has been proposed.
