Some Magnetic Properties of Vacuum-deposited Coupled Films

The magnetic properties of vacuum-deposited multilayer films constructed in a closed-flux configuration in an integrated structure have been studied as a function of: a) film thickness; b) substrate temperature, and c) the character of the conductor metals. It is found the static magnetic properties of the magnetic layers depend on the material in the previous layers as well as the thickness and deposition temperature of those layers. Techniques of optimizing and controlling the magnetic properties are discussed.
