Modification of spin coating method and its application to grow thin films of cobalt ferrite

Spin coating method has been modified to widen its scope for applications. The film deposition assembly is suitably designed. With this modification, it is possible to use common inorganic chemicals in the form of their aqueous solutions as starting materials to grow thin films of binary/ternary oxides. This method is applied to grow thin films of cobalt ferrite. The structure, morphology and magnetic properties of thin films of cobalt ferrite have been determined by using X-ray diffraction, Scanning electron microscopy and vibrating sample magnetometer respectively. The results show that the present technique is useful to deposit thin films of cobalt ferrite, which are qualitatively comparable to the films grown by other wet chemical techniques.
