Ferromagnetic resonance in Co/Pt multilayers
Out-of-plane angular dependence of ferromagnetic resonance spectra was measured in sputtered Co/Pt multilayers and analyzed with the Landau-Lifshitz-Gilbert equation.The effective demagnetizing field 4πMeff is found to increase with decreasing tpt and decreasing 1/tCo,which can be considered as a result of interplay between the interlayer eoupfing and a lowdimensional effect.The g factor increases with increasing tpt and decreasing tCo,indicating contribution of spin-polarization of Pt atoms and additional contribution of orbital moment of Co atoms.The in-plane resonance line-width increases with decreasing tCo and increases with increasing tpt.
