| Abstract: | Structural and magnetic properties of LaCrO3, La0.95CrO3, La1.05CrO3, LaCr0.95O3 and LaCr1.05O3 reported in this work. These series of perovskite samples were prepared by combustion synthesis and were characterized by X-ray diffraction (XRD), physical property measurement system (PPMS) techniques to exam the effect of different doping level on La and Cr on physicochemical properties. Comparing with the original sample LaCrO3 with a predominant antiferromagnetic phase transition near 295 K, others show an approximate but unequal value due to the structural changes. Investigated by Rietveld analysis, we observed this change which will affect the distortion angle of the CrO6 octahedral to further influence the magnetic structure and causes the shifting of magnetic conversion temperature. |
