Superconducting Properties of Bi sub 2 (La sub x Ln sub 1--x ) sub y Ca sub 3--y Cu sub 2 O sub z (Ln = Y, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er and Tm)
Oxide superconductors, Bi sub 2 (La sub x Ln sub 1--x ) sub y Ca sub 3--y Cu sub 2 O sub z (Ln = yttrium or rare-earth element), have been synthesized by doping an additional rare-earth element in the Bi--La--Ca--Cu--O compounds. The zero resistivity superconducting transition temperature of the sam...

| Zusammenfassung: | Oxide superconductors, Bi sub 2 (La sub x Ln sub 1--x ) sub y Ca sub 3--y Cu sub 2 O sub z (Ln = yttrium or rare-earth element), have been synthesized by doping an additional rare-earth element in the Bi--La--Ca--Cu--O compounds. The zero resistivity superconducting transition temperature of the sample with x = 0.5 and y = 0.5 increased by approx 20K to be 45K when compared with the Bi--Ln--Ca--Cu--O (Ln = La, Nd and Pr) superconductors. , . 5 ref.--AA |
