本発明は非晶質合金材料にかかわり、時に高飽和磁束密
度、高透龜率である非晶質強磁性合金に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to amorphous alloy materials, and in particular to amorphous ferromagnetic alloys with high saturation magnetic flux density and high permeability.

討が盛んに行われている。Normally, alloys have a crystalline structure in a solid state, but under special conditions such as rapid cooling from a liquid state, an atomic structure that does not have a crystalline structure similar to that of a liquid can be obtained even in a solid state. Such alloys are called amorphous alloys, and it has become clear in recent years that some of them have very excellent mechanical properties, corrosion resistance, and magnetic properties depending on their composition. Among them, among those based on Co, there are compositions in which the saturation magnetostriction constant 5 is close to zero, and applications are being actively investigated, particularly for magnetic head applications.

-Temperature [Tc, crystallization temperature Tx, and magnetic flux density vary depending on the content of amorphous forming elements (in this case, Ti, Zr, Hf, and Y). If the contents of Ti, Zr, Hf, and Y are reduced, the magnetic flux density will increase. At the same time, KTc also increases.

れている。However, on the other hand, as Tx decreases, K Tc > Tx, which is necessary for achieving high magnetic permeability, Tc < Ta < Tx
It is believed that the retention of Ta at such a temperature and the subsequent rapid cooling treatment will become a national problem.

案されているが、方法が繁雑であり量産的でない。In order to obtain high magnetic permeability with a composition such that TC>TX, a method of heat treatment in a rotating magnetic field (Ta<Tc) has been proposed, but the method is complicated and cannot be mass-produced.

本発明は、このような従来材料の欠点を克服し高い飽和

合金を提供することを目的とする。For these reasons, there is currently an upper limit to the magnetic flux density of zero magnetostrictive CO-based high permeability materials, which is 9.5KG for Bs.
The object of the present invention is to overcome the drawbacks of such conventional materials and provide a CO-based amorphous alloy that has high saturation magnetic flux density and high magnetic permeability.
