Abstract :
Summary form only given. Ferromagnetic resonance is a useful tool to study interlayer exchange coupling of multilayers. However, the ferromagnetic resonance (FMR) spectrum becomes complicated when the thickness of the magnetic layer and the number of bilayers are large. We recently developed a model using Hoffmann boundary conditions to explain the resonance spectra in such cases. In this report, we study the multimode resonance observed in (t/sub Co//t/sub Zr/)/sup 8/ multilayers, in as deposited and thermally treated conditions and demonstrate that this model can be used to obtain quantitative values of the interface roughness (or mixing).
