Liyanawaduge, Shiva KumarSingh, Anuj Kumar, V. Awana, H. Kishan] The superconducting properties and AC/DC magnetic properties of YBa2Cu3−x Zn x O7−δ , (x=0.0, 0.01, 0.03, 0.05, 0.10 and 0.15) compounds were investigated. Samples were synthesized through solid-state reaction route. X-ray diffraction data confirms the single-phase orthorhombic/tetragonal crystallization for the studied samples. Thermo-Gravimetric Analysis (TGA) was done for pure and Zn-doped YBa2Cu3O7−δ (YBCO) samples. Results reveal that at higher dopant levels the doped samples are more oxygen-deficient than the undoped ones. The superconducting properties of YBa2Cu3−x Zn x O7−δ system always enhance with addition of oxygen to Cu-O chains, which causes enhancement of superconducting carrier density together with orthorhombic structure. Zn substitution causes an overall reduction of superconducting condensation energy with systematic degradation of superconducting properties like T c and J c. This occurs via induced non-homogeneity of hole carrier density created by extended nature of perturbation on electronic structure in CuO2 planes and its weak-link type behavior. AC susceptibility measurement reveals that Zn doping reduces the inter-granular couplings. Scanning Electron Microscope (SEM) images indicate that increment of average grain size with increasing of Zn concentration.
