STRUCTURAL AND MAGNETIC PROPERTIES OF Gd1-xBixFeO3

This work presents the synthesis of the Gd1-xBixFeO3 system by the combustion method at a temperature of 650°C using citric acid, the doping with Bi3+ took values from x=0.0 to x=0.14 with an increase of 0.02 per sample. The structural characterization of the system was carried out with the application of X-Ray Diffraction (XRD), which by Rietveld refinement showed a perovskite-type compound with orthorhombic structure, Pbnm space group, preferential orientation in the (112) plane and no secondary phases. The micrographs SEM show the presence of particles with irregular shape and average particle size between 0.092 to 0.24 µm. Finally, the magnetic analysis showed that the materials obtained exhibit anti-ferromagnetic properties with ferromagnetic components.
