Fabrication and Characterization of Cobalt/Iron Composite Coatings
MetadataShow full item record
Cobalt/iron composite coatings are used in micro-equipments due to their high magnetic saturation values and Curie temperatures, as magnetic nanoparticles capable of killing cancer cells, for magnetic data storage and magnetic resonance imaging (MRI) and in coatings, plastics, nanowire, nanofiber and textiles as well as in certain alloys and in catalyst applications. Cobalt/iron composite coatings were prepared by using two types of solution consisting of oleic acid in diphenyl ether and cobalt formate strongly stirred then centrifuged and drayed. Obtained coatings were subjected to chemical and structural analysis by using EDAX and XRD techniques. Some magnetic characteristics have been estimated by drawing the hysteresis loop for various thicknesses of coatings.
