Crucial role of sol-gel synthesis in the structural and magnetic properties of LaFe0.5(Co/Ni)(0.5)O-3 perovskites

Abstract

Iron-based perovskites LaFe0.5M0.5O3, with the orthorhombic (S.G. Pbnm) and rhombohedral (S.G. R-3c) structure for M=Co and Ni, respectively were synthesized using the sol-gel method, in contrast to the literature results. Magnetic investigations reveal that LaFe0.5Co0.5O3 is a canted antiferromagnet and reaches a magnetic transition of 370 K, i.e., much above the 300 K value observed by previous authors, whereas LaFe0.5Ni0.5O3 is antiferromagnetic at low temperature. [GRAPHICS] . The sol-gel synthesized LaFe0.5Co0.5O3 perovskite to be stabilized at room temperature with a pure orthorhombic phase. The magnetization behavior reveals the perovskite is canted antiferromagnet at low temperature.
