A method for increasing the coercive force of a film material, in which multilayer Pt/Co compositions are deposited in a vacuum by magnetron sputtering at room temperature on a thermally oxidized Si(001) substrate. At the same time, separate nanoscale layers of Pt and Co are deposited in the presence of an additional intermediate nanoscale layer of Au.
The disclosed utility model relates to the field of electrical industry and is a method of increasing the coercive force of a Co/Pt-based film material for magnetic information storage means with high recording density and highly sensitive magnetic sensors.
