Synthesis and characterization of ferromagnetic transparent conductive films

The ferromagnetic transparent conductive (FTC) films were fabricated by introducing a magnetic Fe thin film into aluminum-doped zinc oxide (AZO) matrix using magnetron sputtering apparatus. The room temperature (RT) ferromagnetism was observed in all samples prepared at different substrate temperatures (Ts = RT, 200 and 300 °C) and an anomalous magnetization characteristic was observed. There were turning points in the hysteresis loops. Evolution of optical and electrical properties of the FTC AZO/Fe/AZO composite films as a function of substrate temperature has been analyzed.
