Effect of Sr-doped on thermal properties of nanoparticle (La,Sr)FeO3

Structure and thermal properties of La1-xSrxFeO3 have been studied. (La,Sr)FeO3 was synthesized by sol-gel method result in powder form. Structural study was carried out using X-Ray Diffraction (XRD) and TEM. XRD characterization for all samples show orthorhombic perovskite structure. The crystallit...

Summary:Structure and thermal properties of La1-xSrxFeO3 have been studied. (La,Sr)FeO3 was synthesized by sol-gel method result in powder form. Structural study was carried out using X-Ray Diffraction (XRD) and TEM. XRD characterization for all samples show orthorhombic perovskite structure. The crystallite size of the materials lie in the range of 20-40 nm as calculated by using Schrerrer's formula which is also supported by TEM images. The thermal properties were characterized by using DSC. DSC curves show increasing of Neel temperature with addition of Stronsium. Average specific heat capacity was also calculated.
