Highly crystalline corundum-structured $\alpha$-(Ga1-xFex)2O3 alloy thin films were fabricated on $c$-plane sapphire substrates by using a mist chemical vapor deposition method. The full-widths at half maximum of X-ray diffraction rocking curves were smaller than 100 arcsec for the entire range of $x$ from 0 to 1. Optical band gaps were artificially tuned to a value between those of $\alpha$-Ga2O3 and $\alpha$-Fe2O3, that is, 2.2 and 5.3 eV with changing the Fe content $x$ in the films. Magnetic measurements revealed ferromagnetic properties of a $\alpha$-(Ga1-xFex)2O3 ($x = 0.24$) thin film at 110 K.
