Abstract
Description
Sr+2Fe+2As+SrF2→2SrFFeAs
<SrFFeAsの合成例1>
Sr(粒径10〜500μm)、Fe(粒径1〜100μm)、As(粒径1〜100μm)、SrF2(粒径1〜100μm)の各粉末をSr:F:Fe:Asの原子比が1:1:1:1:となるように酸素濃度0.1ppm未満、湿度0.01%程度のグローブボックス中で乳鉢を用いて乾式混合した。約1gの混合物を真空中、400℃で12時間仮焼し、次いで、1000℃で12時間加熱して焼結した。焼結体を粉砕して粒径5〜100μmの粉末とし、得られた粉末を封管し、真空中、1000℃で12時間焼結した。
Laを上記合成例1の原料混合粉末に対して、La金属粉末(粒径10〜500μm)を、Sr金属に対して5原子%、10原子%、20原子%ドープした3種類の混合粉末を作成し、上記合成例1と同じ条件で焼成し、3種類のSrFFeAs:La焼結体を合成した。
