Resumo |
It is possible to substitute Bi in the superconducting BaPb0.75Bi0.25O3 by Sb or Te without destroying the superconductivity. With Sb, a continuous series of solid solutions BaPb0.75Bi0.25?ySbyO3 (0 less-than-or-equals, slant y less-than-or-equals, slant 0.25) exists, while with Te, perovskite BaPb0.75Bi0.25?yTeyO3 exists only upto y = 0.15. With increasing substitution by Sb or Te, Tc decreases continously in both the systems. Superconductivity with a maximum Tc of 8K is found in Ba0.9La0.1Pb0.9?yBiyTl0.1O3 for y = 0.25. |
