Based on Co, Fe, Mn and semi-metals (B,
This study relates to improving the properties of amorphous magnetic alloys composed of Si).

な観点にたつとアモルフアス合金のTxをさらに
高める必要がある。 The inventors discovered that when Mn is added to a Co-Fe-M amorphous magnetic alloy (M=B, Si),
Increase crystallization temperature (Tx) and reduce saturation magnetization (σ S )
It has been found that an alloy with a high magnetostriction (λ S ) and an extremely small amount can be obtained. However, in order to apply amorphous alloys to electronic components, they must have characteristics that can withstand various harsh environments. From this point of view, it is necessary to further increase the Tx of amorphous amorphous alloys.

At least one selected from the group consisting of Ta and Mo
This is based on the discovery that the addition of two elements can further significantly increase Tx. this
Improvements in Tx will make the application of amorphous magnetic alloys much easier.

An alloy of Co 71.5 Fe 2.5 Mn 3.0 Si 8 B 15 , that is, X=
The difference in Tx (ΔTx) is calculated based on Mn. From this figure, if we use Mn, that is, group a, as the standard, when we add Hf, Nb, Ta, Mo, etc.
It was found to be effective in increasing Tx. The most effective elements are Nb, Ta, and Mo. moreover,
The most effective feature of the present invention is that the proportion of vitrifying elements (B, Si) in the amorphous alloy composition,
In other words, it has become possible to significantly reduce the value of vitrification element/(3d transition metal + vitrification element). Specifically, it became possible to make the alloy amorphous even when the proportion of the vitrifying element was 5 at %. It has been found that this can significantly increase saturation magnetization.

も、ｚ30とすることが望ましい。 (Co, Fe) 100-xyz Mn x X y M z (where X is at least one selected from the group consisting of Hf, Nb, Ta and Mo, and M is at least one selected from the group consisting of B and Si In 1), an amorphous phase is realized at z=5 to 30. When y is smaller than 0.01, the effect of increasing Tx is poor, and when it is larger than 5, although the effect of increasing Tx is large, σ S decreases significantly, which limits its use as a magnetic alloy. In particular, in recent years, with the advent of so-called metal tapes, magnetic cores for magnetic heads that record on high coercive force tapes have a high saturation magnetic flux density ( BS ).
alloys are required. For this reason as well, it is desirable to use z30.
