This paper reports the synthesis and characterization of Bi1-x Lux FeO3 (x = 0.00, 0.02, and 0.04) produced by solid-state reaction, in order to evaluate the influence of lutetium on the structural and magnetic properties of bismuth ferrite (BiFeO3). The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and magnetic analysis by vibrating sample magnetometer (VSM) in the temperature range from 50 to 320 K. The obtained results allowed confirming the formation of crystalline materials of rhombohedral structure, space-group R 3 c (161), defined morphology and particle sizes between 2.25 and 4.50 µm. The Lu3+ insertion in the structure caused an increase in magnetization, purity of BiFeO3, and a decrease in the synthesis temperature as compared with the reported in the literature.
