Abstract
(EN)
To reduce the phase transition temperature at which an LMO crystal lattice, which constitutes the oxide layer serving as an interlayer or as a part of an interlayer, is a cubic crystal, the present invention provides a base material for a superconductor wire material comprising an oxide layer (LMO layer (22)) primarily having a crystalline material represented by the compositional formula Laz(Mn1-xMx)wO3+δ (where M is at least one element selected from Cr, Al, Co, and Ti; δ is the oxygen nonstoichiometry; 0 < w/z < 2; and 0 < x ≤ 1).
(FR)
Cette invention concerne un matériau de base pour matériau de fil supraconducteur permettant la réduction de la température de transition de phase à laquelle un réseau cristallin LMO qui constitue la couche d'oxyde servant de couche intermédiaire ou faisant partie d'une couche intermédiaire, est un cristal cubique. Ledit matériau de base pour matériau de fil supraconducteur comprend une couche d'oxyde (couche de LMO (22)) principalement constituée d'un matériau cristallin répondant à la formule Laz(Mn1-xMx)wO3+δ (où M est au moins un élément choisi parmi Cr, Al, Co et Ti ; δ est la non-stoechiométrie en oxygène ; 0 < w/z < 2 ; et 0 < x ≤ 1).
(JA)
 中間層又は中間層の一部としての酸化物層を構成するLMOの結晶格子が立方晶となる相転移温度を低くする。 超電導線材用基材が、組成式がLa(Mn1-x3+δ(M=Cr,Al,Co及びTiから選ばれる少なくとも1つであって、δは酸素不定比量であり、0<w/z<2、0<x≦1である)で表される結晶材料を主体とする酸化物層(LMO層(22))、を含む。
