Abstract
Abstract Novel alloys composed of two immiscible metals are made by vapor-depositing the metals simultaneously onto a suitable substrate. By way of example, alloys of iron and bismuth or cobalt and bismuth may be produced according to this invention. Many of the novel alloys have useful ferromagnetic and magneto-optical properties.
