Abstract:

Well-dispersed nanoscale textured chromium oxide particlesthin films can be fabricated under certain conditions by laser-induced solution deposition LISD from organic solutions and by using selective organometallic chemical vapor deposition OMCVD. The fabricated nanoparticlesthin films are characterized by scanning electron microscope SEM, EDX, X-ray diffraction, and magnetic measurements. We have successfully demonstrated that the LISD and OMCVD are unique techniques for fabricating uniformly-distributed thin films but anisotropic chromium oxide particles, which can be used in electro-magnetic devices. The magnetization measurements show that both types of chromium oxides are presented and that the Curie temperature Tsub c and the saturation magnetization field may be adjustable by controlling the stoichiometry.
