The effect of a neighboring metal layer on the high-frequency characteristics of a thin magnetic stripe
The spin-wave spectrum of a ferromagnetic stripe placed above a metallic layer with finite conductivity is studied by using the magnetostatic Green’s function formalism. It is shown that the frequency and linewidth of the resonances are uniquely determined by complex, mode-dependent demagnetization factors. The formalism developed is used to analyze the resonance characteristics of the magnetic stripe as a function of its width and separation from the metallic layer.Delft Institute of Microelectronics and Submicron TechnologyElectrical Engineering, Mathematics and Computer Scienc
