• Mossbauer measurements were made on ferromagnetic Fe_3Si and Fe_5Si_3 to investigate the magnetic structure. In the ordered crystal of Fe_3Si, two internal fields were found to be 320 kOe and 205 kOe at liquid nitrogen temperature, corresponding to the two crystallographically different sites, Fe(I) and Fe(II). Since Fe(II) has a small magnetic moment, a low internal field and a large isomer shift, its electronic structure may be fairly modified by a formation of covalent bond with Si atom. On the other hand, the situation of Fe(I) seems to be little changed from that of Fe atom in pure iron. Fe_5Si_3 also has two different sites and two internal fields of 230 kOe and 130 kOe at liquid nitrogen temperature. Both kinds of Fe seem to be considerably different from Fe in pure iron.
