    摘要: Disclosed is a superconducting compound which has a structure obtained by partially substituting oxygen ions of a compound, which is represented by the following chemical formula; LnTMOPh [wherein Ln represents at least one element selected from Y and rare earth metal elements (La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu), TM represents at least one element selected from transition metal elements (Fe, Ru, Os, Ni, Pd and Pt), and Pn represents at least one element selected from pnictide elements (N, P, As and Sb)] and has a ZrCuSiAs-type crystal structure (space group P4/nmm), with at least one kind of monovalent anion (F−, Cl− or Br−). The superconducting compound alternatively has a structure obtained by partially substituting Ln ions of the compound with at least one kind of tetravalent metal ion (Ti4+, Zr4+, Hf4+, C4+, Si4+, Ge4+, Sn4+ or Pb4+) or a structure obtained by partially substituting Ln ions of the compound with at least one kind of divalent metal ion (Mg2+, Ca2+, Sr2+ or Ba2+). The Tc of the superconducting compound is controlled in accordance with the ion substitution amount.
