【産業上の利用分野】
本発明は、耐熱樹脂層が形成された非晶質合金薄帯およびその製造方法に関する。
【０００２】
【従来の技術】
非晶質合金薄帯は、各種金属を原材料に溶融状態から急激に冷却することで製造される非結晶の固体であり、通常は厚さ約０．０１〜０．１ミリメートル程度の薄帯である。これら非晶質合金薄帯においては、原子は配列に規則性がないランダム構造であり、軟磁性材料として優れた特性を有している。特にＣｏ元素を含むＣｏ系非晶質合金薄帯は、高い透磁率を特徴とする材料であり、種々の磁気応用部品、例えばインダクタンス、各種コイル、各種トランス、ノイズフィルター、磁気センサー、磁気ヘッド、アンテナ、電波吸収体、モーター、各種コア、配線基板など、幅広い分野において用いられることが期待されている。
【０００３】
非晶質合金薄帯は、その優れた磁気特性を発現させるために、予め所定の焼鈍熱処理を施す方法が一般に用いられている。焼鈍熱処理の条件は発現させたい磁気特性や非晶質合金の種類によって異なるが、概ね不活性雰囲気下において温度３００〜５００℃程度、時間０．１〜１００時間程度の高温長時間で行われることが一般的である。ところが焼鈍熱処理によって優れた磁気特性を発現する反面、極めて脆弱な薄帯となり、物理的に取り扱いにくくなる問題を抱えている。
