M. Charles Robert, S. Sasikumar, S. Saravanakumar, R. Saravanan

The present work focuses on the multiferroic gallium iron oxide compound which could be a good candidate for magnetic storage applications. In this study, the poly crystalline samples of Ga2-xFexO3 (x=0.8, 1.0, 1.2) were synthesized using the standard solid state reaction method. The prepared samples were characterized by powder X- ray diffraction and the powder profile pattern was studied using the Rietveld refinement technique. The average crystallite sizes were evaluated using the Debye Scherrer’s formula and found to be in the range of nanometers. The magnetic properties were studied by using the vibrating sample magnetometer (VSM). The surface morphologies were analyzed by scanning electron microscopy (SEM). The elements present in the sample were verified by using EDS spectra. The band gap energy of Ga2-xFexO3 was evaluated using UV-Visible data.
