JeyaprakashB.G. 1220121216Thin film of spinel ferrite has wide range of application such as magnetic sensor, reading head for magnetic recording media, switch mode power supplies, deflection yoke rings and spintronics devices. These wide applications are due to its high permeability, large resistivity, relatively high magnetization and low coercivity. In the present study spinel ZnFe2O4 with good adhesion on glass substrate have been prepared using home built spray pyrolysis unit from mixed zinc and iron nitrates of 1:2 M aqueous solutions. Photograph of the prepared film shows that as film thickness increases, the color of the film changes from golden yellow to red-brown and is due to increase in grain size. X-ray line broadening technique was adopted to obtain grain size and microstrain. It was observed that the surface morphology and optical transmittance strongly depends on film thickness. Band gap of the film varies from 2.08 to 2.70 eV as film thickness decreases. The effect of film thickness on crystalline nature, surface morphology and optical properties were analyzed and reported.]]>Burstein, E.,195493632633Hofmann, M., S.J. Campbell, H. Ehrhardt and R.
