Insoluble binary system thin film

Abstract Insoluble binary amorphous Fe-Ag and FeCo-Ag or slightly soluble crystalline Fe-Cu films were co-deposited. It was established that they were crystallized or segregated after heat treatment. During the treatment, electrical resistivity drastically decreased at 250°C and coercivity surprizingly increased up to 840 Oe as a result of the shape anisotropy.
