Zusammenfassung:
The Heusler compound Co2FeSi is a prospective half-metallic material for
spintronic applications. Defects and antisite disordering play a crucial
role among the factors reducing spin polarization in such materials. To
clarify effects of possible off-stoichiometry, a continuous series of
model solid solutions Co3-xFexSi (0.6 <= x <= 1.4) was investigated by
Fe-57 Mossbauer spectroscopy and Co-59 nuclear magnetic resonance. It
has been shown that the hyperfine magnetic fields on Fe can be used to
monitor Co-Fe disordering in Co2FeSi-based bulk samples and thin films.
