The effect of doping on formation, superconductivity and pinning forces of (Bi,Pb)-2223 was studied for several dopants. They can be subdivided into promoters (Cu, Mn at low doping level of x = 0.1 and Rh) and inhibitors (Mg, Al, Sn, Co, Y, Pd and high substitution levels of Mn and Ni) of the transformation of the precursor material into (Bi,Pb)-2223. According to X-ray diffraction (XRD) studies the...
