Synthesis and Characterization of Nanostructured Iron Oxide Thin Films: structural, magnetic and optical properties

Abstract

Owing to the properties and applications the facile synthesis fabrication of iron oxide thin films with highly controlled structures, uniform morphologies and novel properties has been a field of significant interest In the present work a novel approach for the formation of and#945; Fe2O3 film using polyvinyl alcohol PVA polymer in the precursor solution is presented The effect of synthesis parameter on the structural, magnetic and optical properties band gap and refractive index of and#945; Fe2O3 film has been discussed Further, thus prepared films have been converted to Fe3O4 by reduction and then to and#947; Fe2O3 by oxidation, while preserving the same morphology All the films have been characterized for their structural, morphological and magnetic properties Also, the effect of Magnetic field, Ni2Plus and Co2Plus doping on the growth, morphology and magnetic properties of the nanostructures is studied newline
