✦ Synopsis

Fag--yCu20r (Ln=Y or rare-earth element), have been synthesized by doping an additional rare-earth element in the Bi-La-Ca-Cu-0 compounds. The zero resistivity superconducting transition temperature of the sample with x=0.5 and y=O.5 increased by about 20 K to be 45 K when compared with the Bi-Ln-Ca-Cu-0 (Ln=La, Nd and Pr) superconductors.
