Crystal Structure and Superconductivity of FeSr$_{2}$(Y,Nd)(Cu,Zn)$_{2}$O$_{6+\delta}$

We have prepared the polycrystalline samples of FeSr$_{2}$Y$_ {0.75}$Nd$_{0.25}$(Cu$_{1-x}$Zn$_{x}$)$_{2}$O$_{6+\delta}$ solid solution system (${x}$ = 0, 0.01, 0.02, 0.05) to investigate the Zn substitution effects. The DC magnetization measurement results showing the samples exhibited decreasing in T$_{c}$ while increasing the Zn content, ${x}$, and the superconductivity was disappeared around ${x}$ = 0.05. Crystal structure has been analyzed by using X-ray and neutron powder diffraction data. The relation between the superconductivity and crystal structure is discussed based on the experimental results.
