Hyperfine fields and Fe magnetic moments in Fe-Ni invar alloys
Description
Moessbauer spectra of Fe1-xNix with x=0.40, 0.35 and 0.32 were taken at various temperatures and fitted with Bhf distributions. The P(Bhf) curves generally show a peak and a low-field tail. The peak B* and the average anti B were obtained in the T→0 limit. Fe moments were deduced from these data with help of a semiempirical equation. While the average anti μFe decreases with x (invar anomaly), a large fraction of Fe atoms retain the strong moment (≅2.7 μmB) typical of Ni-rich alloys. This result is consistent with a two-states model for invar. (orig.)
