A. Slawskawaniewska et Jm. Greneche, MAGNETIC INTERFACES IN FE-BASED NANOCRYSTALLINE ALLOYS DETERMINED BY MOSSBAUER SPECTROMETRY, Physical review. B, Condensed matter, 56(14), 1997, pp. 8491-8494
Mossbauer investigations of Fe89Zr7B4 nanocrystalline material, perfor
med over the temperature range 4.2-550 K and in applied magnetic field
s, are presented and interpreted in terms of the crystalline, amorphou
s, and interfacial contributions. The results obtained indicate that t
he interfaces exhibit structural as well as spin disorder with the the
rmal evolution of the mean hyperfine field similar to that of the crys
talline bcc-Fe phase.
