“…However, as reported in Ref. [4], such improvement was not observed in our measurements; this might have been because the variation was too small and/or because the chemical composition of the amorphous phase also changed (as will be discussed next), modifying its magnetostriction constant.…”

“…It is well known that the magnetization is coupled to the stress by the magnetostriction constant. For this reason, the easy direction of a positively magnetostrictive ribbon is oriented perpendicular to the ribbon plane; however our magnetostriction measurements did not contribute to the understanding of this behaviour since no significant change was found when Nb was gradually replaced by Mo [4].…”

The study of magnetostrictive properties of these alloys showed no significant change in magnetostriction, but proved their potential in technical application . Further study by Mossbauer spectrum and ab initio simulation showed that the estimated saturation magnetization of remaining amorphous phase was higher than that of as‐quenched samples, and additionally in Nb–Mo coexisting samples, a preferential orientation of net magnetization was found .…”

The thermal stability, microstructure, and soft magnetic properties as a function of annealing time were studied for Fe73.5Si13.5B9Cu1Nb3−xMox (x = 0, 1, 2, 3) (atom percent, at.%,) ribbons. It was found that substituting Nb by Mo reduced the thermal stability. After 15 min short time vacuum annealing, Fe73.5Si13.5B9Cu1Nb2Mo1 and Fe73.5Si13.5B9Cu1Nb1Mo2 samples obtained higher permeability and similar coercivity compared to the original Finemet alloy (Fe73.5Si13.5B9Cu1Nb3), Mo substituting Nb reduced the optimum annealing time in Finemet‐type alloys, and meanwhile marginally increased the saturation magnetization. Substituting all Nb by Mo led to the earlier formation of non‐soft magnetic phase, thus deteriorated the soft magnetic properties. XRD and TEM structural analysis showed that in Fe73.5Si13.5B9Cu1Nb2Mo1 and Fe73.5Si13.5B9Cu1Nb1Mo2 samples (annealed for 15 min), nanocrystals ∼10 nm in size were obtained, and the good soft magnetic properties of these alloys could be attributed to the small grain size. The relationship between annealing time, soft magnetic properties, and microstructure was established. Reducing annealing time and temperature to obtain best soft magnetic properties could cut down the production costs of Finemet‐type alloys.

“…In Ref. [9] the magnetostrictive behavior of these samples was investigated, but no influence of the refractory elements exchange on the saturation magnetostriction (l s ) was observed either for the as-quenched ( $ 19 ppm) or for the annealed samples ( $ 2 ppm). The phase transformations occurring during the crystallization process of the alloys were studied in Ref.…”
