of the ${\bm k}$-points in LDA+DMFT-IPT(1) is much smaller than that in TB-LMTO method and the discrepancy of $\mu_{\rm spin}$ for fcc-Ni may be improved by increasing the total number of the ${\bm k}$-points in LDA+DMFT-IPT(1).

Comparison with previous LDA+DMFT results {#sec:Compare_LDA+DMFT_for_FeNi}
-----------------------------------------

Here, we compare the results for ferromagnetic bcc-Fe and fcc-Ni obtained by LDA+DMFT-IPT(1) with other previous LDA+DMFT [@re:Fe-Ni-UJ-paper; @re:Fe-Ni-KKR+DMFT]. Lichtenstein [*et al.*]{} [@re:Fe-Ni-UJ-paper] has used the LDA+DMFT with QMC as an impurity solver. Minár [*et al.*]{} [@re:Fe-Ni-KKR+DMFT] has used the KKR+DMFT with perturbative SPTF (spin-polarized T-matrix+FLEX) as an impurity solver. The energy spectra in LDA+DMFT-IPT(1) show a good agreement with those LDA+DMFT calculations. The existence of Ni 6 eV satellite is also very similar to those LDA+DMFT calculations, presumably much better coincident with the position of the observed spectra. The magnetic moment of bcc-Fe is in good agreement with those LDA+DMFT results. Slightly smaller value of the magnetic moment of fcc-Ni in LDA+DMFT-IPT(1) than previous LDA+DMFT is not due to the use of perturbative IPT approach as an impurity solver but due to insufficient number of ${\bm k}$-points mentioned above. Thus, we can conclude that LDA+DMFT-IPT(1) reproduces reasonable results for ferromagnetic bcc-Fe and fcc-Ni and that LDA+DMFT-IPT(1)
