【発明の詳細な説明】
本発明は非晶質磁性材料に関するものである。
従来よく知られている非晶質磁性材料は磁性金属
原子Ｍといわゆるメタロイド原子Ｘとが合金して
いるMaXbの形の組成をしたものが大部分であつ
た。すなわち、たとえばFe80B20、（Co0.94Fe0.
6）79Si10B11あるいはFe80P13C7などである。これ
らの合金系においてはメタル原子とメタロイド原

る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to amorphous magnetic materials.
Most of the conventionally well-known amorphous magnetic materials have a composition in the form of MaXb, which is an alloy of magnetic metal atoms M and so-called metalloid atoms X. That is, for example, Fe 80 B 20 , (Co 0 . 94 Fe 0 .
6 ) 79 Si 10 B 11 or Fe 80 P 13 C 7 . A major feature of these alloy systems is that the metal atoms and metalloid atoms differ widely in size, and it is said that this is why they can be made amorphous.
しかるにこれら従来型非晶材料においては、構
成原子の大きさおよび原子量が比較的大巾に異る
ためか、磁気特性の経時変化が著しく大きいとう
重大な欠点をもつている。すなわち、Coを主体

にとると、20KHzにおける熱処理直後の実効透磁
率μe＝16000は、150℃にて100時間保持したあと
では約50％劣化してμe＝8000になつてしまうと
いう程のもので、このままでは、たとえば磁気ヘ
ツドのコアとして使うことは全く不可能である。 However, these conventional amorphous materials have a serious drawback in that their magnetic properties change significantly over time, probably because the sizes and atomic weights of their constituent atoms vary widely. In other words, taking the case of CoFeSiB-based high magnetic permeability amorphous material mainly composed of Co, the effective magnetic permeability μe = 16000 immediately after heat treatment at 20KHz becomes approximately 50% after being held at 150℃ for 100 hours. It has deteriorated to the extent that μe = 8000, and as it is, it is completely impossible to use it as the core of a magnetic head, for example.

No. 33453) has an atomic ratio of 8 to 14% zirconium,
At least one of nickel or cobalt 7~
The disclosure discloses an iron-based amorphous alloy with high magnetic flux density and low magnetostriction, the remainder being substantially iron.
本発明は従来材の欠点を除去した全く新しい非
晶質磁性材料を提供するものである。 The present invention provides a completely new amorphous magnetic material that eliminates the drawbacks of conventional materials.
すなわち、本発明の第一の非晶質磁性材料は、
組成式（原子比率で表示）：
（Fe1-x-yCoxNiy）100-aZra
（ただし、０≦ｘ＜１、０＜ｙ≦１、０＜ｘ＋
ｙ≦１かつ２≦ａ≦30（ただし、７≦（ｘ＋ｙ）×
（100−ａ）≦38かつ８≦ａ≦14の場合を除く））で
表されることを特徴とする。 That is, the first amorphous magnetic material of the present invention has the following composition formula (expressed in atomic ratio): (Fe 1-xy Co x Ni y ) 100-a Zra (0≦x<1, 0< y≦1, 0<x+
y≦1 and 2≦a≦30 (however, 7≦(x+y)×
(100-a)≦38 and 8≦a≦14)).
上記の組成範囲は全く新規なものであり、従来

る。 The above composition range is completely new and makes it possible to obtain an amorphous magnetic material without the drawbacks of the conventional ones.
ここに磁性原子としてのFe，CoおよびNiは80

~95%, Zr20~5% are preferable from the viewpoint of magnetic flux density, but Fe, Co,
This is maintained in the range of 70 to 98% Ni and 30 to 2% Zr, and it is practical within this range.
但し、Fe、CoまたはNiの量が70％を割ると磁
束密度が低くなりすぎること、また、Zrの量が

との関係で、Co及び／又はNiが７〜38％かつZr

除外される。 However, if the amount of Fe, Co, or Ni is less than 70%, the magnetic flux density becomes too low, and if the amount of Zr is less than 2%, it becomes difficult to become amorphous, making it impractical. In relation to Japanese Patent Application No. 108078/1983, Co and/or Ni is 7 to 38% and Zr
Excludes cases where 8% to 14%. Therefore, the following cases are excluded.

た。Example 1 An amorphous ribbon with a composition of (Fe 0 . 15 Co 55 Ni 0 . 3 ) 90 Zr 10 was prepared and its magnetic properties after heat treatment were measured; B 10 = 10.5 KG, Hc = 0.2 Oe. It was hot. This was aged at 150°C for 100 hours and the magnetic properties were measured again, but it was found that there was almost no deterioration.

判明しており、工業上価値の大きなものである。 According to research conducted by the inventors, the alloy of the present invention not only has excellent stability, but is also easier to manufacture and has a higher magnetic flux density than conventional amorphous materials.
It has excellent corrosion resistance and abrasion resistance, has a relatively high Kyrie point, and has magnetostriction that can be selected appropriately according to each application, making it suitable for magnetic head materials for audio, VTR, and computer applications, and other electromagnetic transducers. It has been found to be an extremely superior material and has great industrial value.
本発明において、Zrは非磁性元素であるので、

が得られる。一方、合金にZrを14at％より多く、
30at％以下含有させれば、合金の非晶質化が容易
である。 In the present invention, since Zr is a non-magnetic element,
When it is less than 8at%, an alloy with particularly high magnetic flux density can be obtained. On the other hand, if the alloy contains more than 14at% of Zr,
If the content is 30 at% or less, the alloy can be easily made amorphous.
