The study investigated the effect of a small alloy addition (1 atomic %) in alloys Fe61Co10Y8Nb1B20, b - Fe61Co10Y8Zr1B20, c - Fe61Co10Y8W1B20, d - Fe61Co10Y8Mo1B20 on the shape of the Mossbauer spectrum and on the distributions of hyperfine field induction on 57Fe obtained from their numerical analysis. The line factor A [2.5] was also determined in the Zemman�s sextet, which is an indirect measure of ordering for the texture of the spins occurring in the volume of alloys. Based on the analysis of the results, it was found that the Mossbauer spectras are typical of amorphous alloys and the hyperfine field distributions are bimodal.

The magnetization and Fe hyperfine fields of the series of amorphous alloys Fe80−xMoxB20 for x = 0, 2, 4, 7, 10, and 14 have been investigated. The magnetization at 4.2 K decreases from a value of 180 ± 2 emu/g for Fe80B20 to 79 ± 2 emu/g for Fe66Mo14B20 (1 emu = 10 A). The Fe hyperfine field is 2.91 × 105 Oe in Fe80B20 and shows a decrease of approximately 8 × 103 Oe/at. % of Mo (1 Oe = 79.6 A/m). The hyperfine field distributions show a growing low-field component with increasing x. Results are discussed in terms of previous measurements on similar alloys and the local environment of Fe atoms in transition metal glasses.

Abstract Thermal treatment, undertaken at just below the crystallization temperature, has led to nanocrystallization and has had a significant impact on the shape of the hyperfine field induction distributions of Fe62Co10Y8B20 alloy and on its soft magnetic properties. In the amorphous ferromagnetic alloys, it is possible to indirectly determine the effect of the structure stresses, resulting from the presence of structural defects, on the soft magnetic properties of these materials. It has been found that a change in the parameters associated with the presence of structural defects affects the shape of the hyperfine field distributions of 57Fe.
