Our purpose in the present study was to elucidate the origin of the giant TMR ratio of Co<sub>2</sub>(Mn,Fe)Si (CMFS) MTJs with lightly Fe-doped, Mn-rich CMFS electrodes. We took into consideration the valence electron number/f.u., Z<sub>t</sub>, of off-stoichiometric Co<sub>2</sub>MnSi (CMS) expressed as Co<sub>2</sub>Mn<sub>α</sub>Si<sub>ß</sub> decreases… CONTINUE READING
