摘要：

The Present study focuses on the structural and magnetic properties of Gadolinium orthoferrite specimen synthesize using one-step sol-gel auto combustion method. The Rietveld refinement of XRD pattern confirms the orthorhombic structure of the GdFeO3 nanomaterial with the Pbnm space group. SEM analysis reveals that the particles exhibit dimensions within the nano regime. FTIR and Raman spectra show the presence of all the modes associated with GdFeO3. Magnetic isotherm recorded at room temperature shows the antiferromagnetic behaviour of the sample. Magnetic field-induced spin reorientation transition is observed to be broad around 5 K. The fitting of modified Curie-Weiss law results in larger value of mu eff as compared to theoretical value. The observed anomalous results, in contrast to earlier studies, may have originated from modifications in the microstructure.
