FeZrBCu nanocrystalline materials obtained by controlled crystallization of the amorphous alloy are composed of bcc-Fe grains (10 nm in diameter) embedded in a residual amorphous matrix. In this article it has been shown that in such a mesoscopic system the interfaces exhibit identifiable properties that differ from those of the interior. In the M{umlt o}ssbauer spectra, besides of contributions from bcc phase and that of the residual amorphous matrix, an additional component was observed and attributed to the crystalline grain-amorphous matrix interfaces. The effect of the surface layer on the effective magnetostriction is also presented and discussed. {copyright} {ital 1997 American Institute of Physics.}
