Description
.05〜1.0at%より構成される磁性薄膜およびスパッタリングターゲットまたは蒸着材料を提供するものである。
Ni−P合金チップ等の合金チップの少なくとも1種を前記の組成割合となるようにして載せた複合ターゲットであってもよい。また、Fe、Cu及びNiを単体で複合ターゲットの一部として使用することもできる。
Ptターゲット上にFe−P合金チップ、Fe−Cu−P合金チップおよび/またはFe−Ni−P合金チップを載せることにより複合ターゲットを準備した。この複合ターゲットをRFマグネトロンスパッタ装置にセットし、ソーダガラス基板上に成膜し、下記表1に示す実施例1〜6および比較例2の試料を作製した。なお、実施例1および比較例2では、Ptターゲット上にFe−P合金チップを載せ、基板を200℃に加熱した。また、実施例2〜6では、Ptターゲット上にFe−Cu−P合金チップもしくはFe−Ni−P合金チップを載せ、基板は加熱しなかった。
の結果を下記表3に示す。
