Preparation of Magnetic Transparent Conducting ZnO:Al/Fe65Co35/ZnO:Al Multifunctional Films

In this work, we attempted to construct a ferromagnetic transparent conducting film through multilayer approach. The ferromagnetic transparent conducting ZnO:Al/Fe65Co35/ZnO:Al tri-layer structure films were fabricated by inserting a middle magnetic Fe65Co35 thin layer into ZnO:Al matrix using multi-target magnetron sputtering apparatus at the substrate temperature of 300 °C. The ferromagnetism was observed by vibrating sample magnetometer (VSM) at room temperature, and the in-plane hysteresis loops revealed that the magnetic properties strongly depended on the Fe65Co35 layer thickness. The inserted middle Fe65Co35 thin layer played an important role in providing the ferromagnetism and decreasing the resistivity of the multifunctional films.
