Synthesis, Structure and Magnetic Behavior of Ce-Doped Lanthanum Manganite Ceramics
N. Thenmozhi, R. Saravanan
The ceramic perovskite La0.88Ce0.12MnO3 has been synthesized using the solid state reaction method. The grown sample was characterized for its structural, optical, and magnetic properties using powder X-ray diffraction, UV–visible spectra and vibrating sample magnetometer (VSM) measurements. The Rietveld analysis of the X-Ray diffraction (XRD) profile clearly indicated that the XRD pattern is well fitted with an orthorhombic structure. The electronic structure of the synthesized sample has been studied through the maximum entropy method. The optical study gives the direct band energy gap value as 2.106 eV. VSM measurements, at room temperature show paramagnetic behavior of the prepared sample.
