Double perovskite, La2CoFeO6(LCFO) has been successfully synthesised by the glycine-nitrate combustion method in the present work. X-ray diffraction (XRD), FTIR and Raman spectra were used for the structural investigations of the prepared LCFO nanoparticles. XRD data reveal the formation of pure phase of LCFO double perovskite in the rhombohedral phase with an average crystallite size of ~32 nm. Field emission scanning electron microscopy (FESEM) images show the honey comb like morphology with well- defined grain boundaries. FTIR and Raman spectra confirm the presence of characteristic bands corresponding to the formation of double perovskite structure. Magnetization curves at room temperature show the weak ferromagnetic nature of LCFO nanoparticles prepared with combustion method. The observed magnetization is attributed to Dzyaloshinskii–Moriya interaction.

摘要

Double perovskite, La2CoFeO6(LCFO) has been successfully synthesised by the glycine-nitrate combustion method in the present work. X-ray diffraction (XRD), FTIR and Raman spectra were used for the structural investigations of the prepared LCFO nanoparticles. XRD data reveal the formation of pure phase of LCFO double perovskite in the rhombohedral phase with an average crystallite size of ~32 nm. Field emission scanning electron microscopy (FESEM) images show the honey comb like morphology with well- defined grain boundaries. FTIR and Raman spectra confirm the presence of characteristic bands corresponding to the formation of double perovskite structure. Magnetization curves at room temperature show the weak ferromagnetic nature of LCFO nanoparticles prepared with combustion method. The observed magnetization is attributed to Dzyaloshinskii–Moriya interaction.
