Abstract:
1. A method for producing the superconducting compound, comprising: dehydrating La mixing La metal, TM metal, and Ph element in a ratio of 1:3:3 to obtain a first mixture, wherein TM is one or more selected from Fe, Ru, Os, Ni, Pd, and Pt; and Ph is one or more pnictide elements selected from N, P, As, and Sb, and sintering the obtained first mixture in a dry inert gas atmosphere, thereby obtaining sintered mixture 1 including LaPh, TM replacing 4-20 mol % of anhydrous La mixing the sintered mixture 1 and the mixture 2 such that molar ratio of La and TM becomes 1:1 to obtain a third mixture, and sintering the obtained third mixture at 1100-1250° C. in an inert gas atmosphere, thereby obtaining a compound, which is represented by a chemical formula of LaTMOPh, oxygen ions of which are substituted with 4-20 mol % F
