Mössbauer and NMR Studies of Site Substitution and Magnetic Structure of $Fe3−xMnxSi$ Alloys

The NMR measurements in $Fe3−xMnxSi$ alloys show increasingly complex spectra for $x > 0.75$ due to overlapping signals from Fe, Si and Mn nuclei in various sites. Mössbauer experiments were undertaken to identify the Fe⁵⁷ resonances. The combined NMR and Mössbauer results have been used to elucidate the site substitution and magnetic structure of these alloys for (⁠$0 < x < 1.75$⁠).
