Fabrication and Characterization of Cobalt/Iron Composite Coatings
Abstract
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.
