To form a layer of polycrystalline ferrite magnetic, optical, cobalt, and a layer made of ferrite of cobalt formed thus

摘要

P is obtained by thin films of polycrystalline ferrite of cobalt, used in particular for applications of magnetic, optical, the fact that a solution of nitrate hydrated iron and cobalt is treated so as to become an aerosol, which subsequently is projected onto a substrate heated. The optical rotation of the magnetic layers thus obtained is equal to several times that of the layers known up to the present application to the magnetic memories. / p
