Novel uniaxially anisotropic magnetic thin films, their manufacture and their application

摘要

Thin films made of amorphous soft ferromagnetic alloy, essentially based on cobalt, which are deposited on the solid substrate, characterised by the fact that they have a magnetostriction and a transverse anisotropy which are essentially zero and that they have in their plane a uniaxial anisotropy field greater than or equal to 80 oersted and a coercive field, in that the direction of the easy magnetisation axis, less than 3 oersted; used as soft ferromagnetic layers and in particular for making planar delay-line domain memories or multi-layer magnetic devices. <IMAGE>
