The effect of the substitution of Cu(1) by dopants on oxygen content and superconductivity in Y(123)

The study of YBa 2Cu 3− x Ag x O 7− y compounds (0.0 < x < 0.5) is carried out. It is shown that Ag substitutes Cu(1) in the lattice up to x = 0.12 and has an effect on the oxygen content and T c even at the low level of doping. The addition of Ag changes the lattice constants of Y(123) so the...

Zusammenfassung:The study of YBa 2Cu 3− x Ag x O 7− y compounds (0.0 < x < 0.5) is carried out. It is shown that Ag substitutes Cu(1) in the lattice up to x = 0.12 and has an effect on the oxygen content and T c even at the low level of doping. The addition of Ag changes the lattice constants of Y(123) so the solubility of oxygen arises at the same preparing conditions. This phenomenon is extended to the doping effect with other elements substituting Cu(1): Au, Co, Fe and Al.
