GaFeO 3 : A Ferromagnetic-Piezoelectric Compound

Piezoelectricity and ferromagnetism have been found to occur simultaneously in the compound Ga(2−x)FexO3. Single crystals of approximately equimolar gallium to iron ratio have been grown from a flux consisting of Bi2O3 and B2O3. X-ray diffraction data on ceramic compositions have shown that the galliumto iron ratio can be varied between x = 0.7 to x = 1.4. Magnetic data showing the shift in magnetic Curie point vs Fe concentration and magnetization vs Fe concentration will be given.
