A new superconductive (Ln)Ba2Cu306.85 ''cocktail'' phase (Ln = Y, Nd, Sm, Eu and Yb)

  • 1. Centre National de la Recherche Scientifique, 31 - Toulouse (France)

Description

The high Tc superconductive (Ln)Ba2Cu306.85 phase contains a ''cocktail'' of five Rare Earths (Y, Nd, Sm, Eu, Yb) equably present (20% each). This phase is orthorhombic, isostructural with YBa2Cu307, the cell parameters being: a=3.833(3), b=3.891(3), c=11.691(7)A. The critical temperature of the superconductive transition of this phase, initially measured in helium (Tc=90 K), is increased after exposure to nitrogen gas (Tc=92 K)

Abstract (French)

(Ln)Ba2Cu306,85 phase supraconductrice comporte un ''cocktail'' de cinq Terres Rares (Y, Nd, Sm, Eu, Yb) dans la proportion de 20% pour chacune d'entre elles. Cette phase, orthorhombique, est isostructurale de YBa2Cu307, les parametres de maille etant : a=3,833(3), b=3,891(3), c=11,691(7)A. La temperature critique de la transition supraconductrice de cette phase, initialement mesuree sous atmosphere d'helium (Tc=90 K), augmente apres exposition de l'echantillon a l'azote (Tc=92 K)
