    摘要: The disclosed superconductive material has a characteristic in accordance with which electrical resistance disappears at a temperature of at least more than the boiling point of 20.3.degree. K. (-252.7.degree. C.) of liquid hydrogen and relates to La-Ba-Cu-O series superconductive material.Said superconductive material consists essentially of a composition having the formula(La.sub.1-x M.sub.x).sub.2 CuO.sub.4-x/2wherein, M=Ba or Ba(Sr, Ca) and x=0.04.about.0.20 as a main body, wherein the material has a K.sub.2 NiF.sub.4 crystal structure.
