Abstract
Magnetic properties of samples of FeGa2O4 have been measured by Mossbauer spectroscopy, neutron diffraction and magnetization techniques. Superparamagnetic behaviour has been found above about 10K, below which temperature long-range magnetic coupling develops. The neutron diffraction results also indicate that in FeGa2O4 spinel, Ga3+ ions do not have preference for either A or B sites in the presence of Fe2+ ions.
