摘要：

The synthesis and characterization of Fe-doped CuAlO2 semiconductor were reported. The samples were synthesized by a simple and cost effective spin-on technique from solid state reaction of Cu2O and Al2O3 on sapphire (001) substrate. Appropriate ethyl-cellulose (EC) and terpineol are useful for the formation of Fe-doped CuAlO2 films. X-ray diffraction (XRD) revealed the growth of pure delafossite CuAlO2 phase ruled out elemental metallic Fe clusters in all the Fe incorporated CuAlO2 films. The existence of ferromagnetism at room temperature is evidenced by well-defined hysteresis loops. Specially, the saturation magnetization (M (s)) values at room temperature have been monotonously enhanced with the increase of Fe composition from 1% to 5%.
