Abstract

Two-layered ferromagnetic alloy films ($Ni_{80}Fe_{20}$, $Co_{90}Fe_{10}$) with a Conetic intermediate soft magnetic layer of different thickness were investigated to correlate the coercivity values and magnetization process with the strength of the hard saturation field. The interpretation of strong, medium and weak coupling is proposed.
