Abstract

We successfully fabricated corundum-structured α-(InFe)2O3 alloy films on sapphire substrates by inserting α-Fe2O3 buffer layers. The ion compositions in the α-(In1-xFex)2O3 films, x, were artificially tuned for the entire range from 0 to 1 by changing the ion precursor composition in source solution. Magnetic measurements revealed that the α-(In1-xFex)2O3 (x = 0.13) alloy film showed ferromagnetism at 5 K.
