Abstract
A high-Tc superconductor YBa2Cu3 Snx07+z was characterized. We observed the existence about 90K superconductivity in variety of compositions. The samples were examined by x-ray diffraction , Mössbauer, SEM and EDS. Their structure are still ABO3 perovskite but part of Cu atoms are displaced by Sn. It was observed that when the x increased the critical current density were increased based on the measurements of magnetic hysteresis.
