Investigation of Structural and Magnetic Properties of GdFe0.5Cr0.5O3 Perovskite Prepared by Solid-State Route

GdFe0.5Cr0.5O3 compound was synthesized through solid-state reaction route, based on stoichiometric mixture of Fe2O3, Cr2O3 and Gd2O3. The X-ray diffraction data showed that GdFe0.5Cr0.5O3 crystallizes in an orthorhombic distorted perovskite structure. High-resolution electron microscopy showed a well-ordered material and confirms the orthorhombic perovskite symmetry. Magnetic susceptibility data reveal a Curie-Weiss behavior in the temperature range 250 − 340 K and the onset of antiferromagnetic interactions with a Neel temperature of 241 K.
