Fabrication And Characterization Of Fe3o4thin Films With Improved Magnetic Properties By Spin Coating Technique

The Fe3O4 thin films were deposited onto glass substrates by spin coating method at various temperatures using FeCl2 4H2O, citric acid monohydrate, ascorbic acid and ethanol absolute were used as starting materials. Structural, morphological and optical properties of Fe3O4 thin films have been studied. The structural studies revealed that the as-deposited Fe3O4 thin films are nanocrystalline in nature with cubic lattice. The morphological investigations show that the total substrate surface is well covered with crack free and homogenous surfaces.
