“…7). The as-spun sample showed a characteristic bimodal distribution for the hyperfine field conforming to the earlier results reported in literature for similar alloys [4,14,15]. The most probable field at around 24 T for the as spun sample may be due to Fe rich regions and the low field peak near 12 T may arise due to the Fe atoms with Mo and Cu as nearest neighbours.…”

“…XPS and SIMS data obtained yet showed that relaxation processes resulted in a significant irreversible alteration of the surface elemental/phase composition and electronic structure of Finemet. An irreversible relaxation process in as-quenched Finemet Fe 73.5 Si 13.5 B 9 Cu 1 Nb 3 was also clearly observed [24] by differential scanning calorimetry when heating was interrupted at 350…”

X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS) were used to study the surface composition and electronic structure of Finemet, Fe 73 Si 15.8 B 7.2 Cu 1 Nb 3 , in the original amorphous state and after gradual heating in vacuum to a temperature of 400• C and cooling back to room temperature. It was found that relaxation processes occurring during heat treatment well below the crystallization onset caused the physico-chemical state of Finemet surface to change irreversibly. In the relaxed alloy, the surface originally covered with the native air-formed oxide was significantly enriched with elemental iron and depleted of other alloy constituents compared with the original state. Yet in the as-quenched state, clustering of copper atoms on the Finemet surface was detected which was enhanced by heating. The thermal treatment resulted in the selective reduction of iron oxides and caused noticeable changes in the valence band structure and the Fe L 3 VV Auger spectrum associated with atomic redistribution.

“…5). The as-spun sample with 0% Al showed a characteristic bimodal distribution [4,[11][12][13][14]. Miglierini et al [12] have made similar observation regarding the hyperfine field distribution of FINEMET alloys and attributed the bimodal distribution to the presence of two distinct types of surroundings for the resonant atom.…”
