PROBLEM TO BE SOLVED: To provide a novel copper oxide compound and a method for producing the same. A copper oxide represented by a chemical formula M m X 2 Sr n-1 Cu n O 2n (O,Z) 2+δ is A first layer (block layer 11) represented by the chemical formula M m X 2 (O,Z) 2+δ and a second layer (superconducting layer 10) represented by the chemical formula Sr n-1 (CuO 2 ) n. Has a crystal structure in which and are alternately laminated, and Sr is present between the crystal planes of CuO 2 . [Selection diagram] Figure 1 |
