Method of preparation, by cathodic sputtering, thin films of a multilayer magnetic substance and silver, with the pharmacological magnetic and / or magneto - optic improved

摘要

Method of preparation of multilayer thin films of a Fe, Co, Ni magnetic substance and their alloys, consisting in depositing the thin films by RF cathode sputtering, for the magnetic substance, with a deposition rate of 2-3 nm/min, and by RF-magnetron cathode sputtering for the silver, with a deposition rate of 6-10 nm/min. The multilayer thin films thus obtained have improved magnetic and/or magneto optical properties, compared to the properties of the magnetic substance. They can be used as a magnetic material in devices using magnetic and/or magneto-optical effects.
