Abstract

　金属基板を構成する元素の超電導層への拡散や中間層のクラックの発生を防止し、かつ超電導層の配向性を向上させる。 　半値幅（ＦＷＨＭ：Δφ）６．５度のＮｉ基合金基板１上に、第１中間層として膜厚１５～１００ｎｍのＣｅ－Ｇｄ－Ｏ系酸化物層２（Ｃｅ：Ｇｄ＝４０：６０～７０：３０のモル比）及び第２中間層として膜厚１００ｎｍのＣｅ－Ｚｒ－Ｏ系酸化物層３（Ｃｅ：Ｚｒ＝５０：５０のモル比）をＭＯＤ法により形成し、さらにその上にＲＦスパッタ法により第３中間層としてＣｅＯ２酸化物層４を膜厚１５０nmに成膜した。この３層構造の中間層の上に、ＹＢＣＯ超電導層５をＴＦＡ－ＭＯＤ法により膜厚は１μｍに成膜した。 　以上のテープ状酸化物超電導体の第１乃至第３中間層のΔφは、それぞれ（６．０～６．５）度、（６．０～６．６）度及び（６．０～６．６）度、ＹＢＣＯ超電導層５の液体窒素中におけるＪｃは１．８～２．２ＭＡ／ｃｍ２の値を示した。
