N2 - The ferromagnetic resonance (FMR) spectra in a NiFe film covered partly with Pt have been investigated. In contrast to the simple Lorentzian spectral shape observed for a plain Ni81 Fe19 film, the FMR spectral shape for the Ni81 Fe19 / Pt film clearly deviates from the Lorentzian shape. This result can be argued in terms of the renormalization of the gyromagnetic ratio affected by the spin pumping effect in the vicinity of the Ni81 Fe19 / Pt interface.
