Figure 2

(a,b) Energy spectra of XFMR and TEY-XMCD signals around the Ni \(L_{2,3}\) edges for (a) Ta(2)[Pt(2)/Py(5)]\(_{6}\) and (b) Pt(10)/Py(30). The XFMR data were obtained at phase delay times of \(t = t_1\) and \(t = t_2\) for Ta(2)[Pt(2)/Py(5)]\(_{6}\), and \(t = t_1^{\prime }\) and \(t = t_2^{\prime }\) for Pt(10)/Py(30) (see Fig. 1d,e). Red and blue lines represent the estimated XFMR spectra obtained by Bayesian inference analysis. The TEY-XMCD spectra are represented by dashed lines. All spectra were normalized to the intensity at the \(L_2\) edge for comparison. Dotted lines indicate values of the intensities at the \(L_3\) edge of the TEY-XMCD signals and the estimated XFMR spectra. Inset in the figure (b) shows Trans-XMCD and XFMR spectra around the \(L_3\) edge for Pt(10)/Py(30). (c,d) Posterior probability distribution of the ratio of \(m_L\) to \(m_S\) (\(r = m_L / m_S\)) obtained by Bayesian inference analysis. The values of r obtained by the TEY-XMCD spectra were also represented as black arrows.
