Cobalt / Palladium magneto-optical multilayer thin film having high coercive force and manufacturing method thereof

摘要

The present invention relates to a cobalt / palladium photomagnetic multilayer thin film for use as a magneto-optical recording medium and a method of manufacturing the same, wherein the modulus of curvature is controlled to form a short-circuited interface and / or between the final Co layer of the Co / The present invention provides a Co / Pd photonic multilayer thin film and a method of manufacturing the same, wherein the Pd buffer layer is deposited on the substrate, thereby forming a complete angle of vertical self-hysteresis line and / or an excellent coercive force.;The present invention relates to a Co / Pd photonic multilayer film in which Co / Pd units having a thickness of 2-3 A and 6-10 A are repeatedly formed on a substrate 10 times or more, wherein the plurality of Co / A Co / Pd photonic multilayer thin film having a high coercive force and a Pd layer having a thickness of 100 angstroms or more deposited between the Co layer of the two layers and the substrate, and a manufacturing method thereof.
