摘要：

An existence of effects connected with the surface of grains in nanocrystalline FINEMET-like Fe72Cu1.5Nb4Si13.5B9 alloy was verified by investigation of hyperfine and magnetoelastic properties. In the Mossbauer spectra (collected both at room temperature and close to T-c of amorphous matrix) a broad, high field component was found, which could be attributed to the grains surface and interface region. Such interpretation is confirmed in magnetostrictive experiment pointing to a high value of surface magnetostriction constant. (C) 2003 Elsevier B.V. All rights reserved.
