  We report the synthesis of alpha-Fe1.4Ga0.6O3 compound and present its
structural phase stability and interesting magnetic, dielectric and
photo-absorption properties. In our work Ga doped alpha-Fe2O3 samples are well
stabilized in alpha phase (rhombohedral crystal structure with space group
R3C). Properties of the present composition of Ga doped alpha-Fe2O3 system are
remarkably advanced in comparison with recently most studied FeGaO3
composition. At room temperature the samples are typical soft ferromagnet, as
well as direct band gap semiconductor. Dielectric study showed low dielectric
loss in the samples with large enhancement of ac conductivity at higher
frequencies. Optical absorption in the visible range has been enhanced by 4 to
5%. This composition has exhibited large scope of tailoring room temperature
ferromagnetic moment and optical band gap by varying grain size and non-ambient
(vacuum) heat treatment of the as prepared samples by mechanical alloying.
