The effect of Pr substitution at sr sites in 110K phase of (Bi-Pb)-Sr-Ca-Cu-O superconducting ceramics / Nazarin Nordin

The effect of magnetic Praseodymium (Pr) substitutional doping at varying concentration into the Strontium (Sr) site in the Bi-Sr-Ca-Cu-0 (BSCCO) high temperature superconductor is investigated. The samples are prepared via solid state reaction method and underwent sintering, annealing and resint...
