FeSr 2 YCu 2 O 6+d with tetragonal Ba 2 YCu 3 O 6+d -type structure exhibits superconductivity around 60 K, only when it is annealed in reduced atmosphere and subsequently in oxidized atmosphere. However, FeSr 2 NdCu 2 O 6+d with the substitution of lanthanoid with large ionic radius for Y do not ex
