also observe flat branches in fcc-Ni at $-6~{\mbox{eV}}$ of both majority and minority spins. These flat bands at $-6~{\mbox{eV}}$ are due to the local multiplet excitations of ${\mbox{d}}^8 {\rightarrow}{\mbox{d}}^7$, where the intensity of the ${\bm k}$-resolved spectrum of majority spin is larger than that of minority spin. This intensity difference causes the strong spin dependence of $-6~{\mbox{eV}}$ satellite in the energy spectrum in Fig. \[fig:dos-Fe-Ni\]-(2b).

The ${\bm k}$-resolved spectrum in bcc-Fe is more diffusive than that in fcc-Ni at around $-3.0~{\mbox{eV}}\sim 0.0~{\mbox{eV}}$ in spite of smaller $U$ for bcc-Fe than fcc-Ni. This comes from that the scattering process by $J$ compared with $U$ is stronger in bcc-Fe than in fcc-Ni since $J/U$ in bcc-Fe is larger than that in fcc-Ni.

The magnetic moment $\mu_{\rm spin}$ of both bcc-Fe and fcc-Ni is almost the same as LDA result. $\mu_{\rm spin}$ of bcc-Fe in LDA+DMFT-IPT(1) result is also in good agreement with experiment, while that of fcc-Ni is slightly smaller than experimental result. This is an artifact due to insufficient number of ${\bm k}$-points to integrate the lattice Green’s function $G({\bm k}, {\omega})$ to obtain the local Green’s function $G({\omega})$ by using generalized tetrahedron method. The adopted value of the total number
