Effects of the Repetition Number on Static and Dynamic Magnetic Properties of Metal/Native Oxide Multilayer Films

The [Fe-Co-Si (2 nm)/native oxide]N multilayer films weredeposited on glass substrate by DC magnetron sputtering. The effect of repetitionnumber N on static and dynamicmagnetic properties of the multilayer films was investigated. Good soft magnetic properties have been obtained inthe multilayer films with repetition number more than 30. Relatively highvalues of the complex permeability and ferromagnetic resonance frequency wereobtained and they can be adjusted by changing the repetition number of themultilayer films.
