In Ga2−xFexO3with the Pc21n orthorhombic structure, owing to the site disorder of Fe ions on the four nonequivalent sites of Fe1, Fe2, Ga1, and Ga2, there exists a significant amount of non-effective Fe ions with no contribution to the ferrimagnetic ordering. These non-effective Fe ions have been found to induce strong frequency dependent suppression of the peak height in the ac susceptibility, demonstrating the frustration effect in the ferrimagnetic ordering background.
