The saturation magnetization M _s as determined from SQUID measurements (right axis) and effective saturation induction 4πM _eff as determined by FMR (left axis) for the \({\bf{Py}}({{\boldsymbol{d}}}_{{\rm{Py}}})|{\bf{Fe}}({\bf{6}}-{{\boldsymbol{d}}}_{{\rm{Py}}})\) structure. Left axis is scaled by 4π to right axis for direct comparison. The dashed line represents a linear fit to the M _s data using eq. (1) and the solid line is a plot of eq. (2) using \({M}_{{\rm{s}}}^{{\rm{Py}}}=817\,{\rm{emu}}/{{\rm{cm}}}^{3}\) and \({M}_{{\rm{s}}}^{{\rm{Fe}}}=1678\,{\rm{emu}}/{{\rm{cm}}}^{3}\). The interface anisotropy as extracted from eq. (9) is shown in the inset.
