| Description |
The effect of suppression of antiferromagnetic order and charge stripes formation mechanism, by Zn3d¹⁰ (S = 0) substitution at Cu3d⁹ (S = 1/2) sites in CuO₂ planes of Cu₀.₅Tl₀.₅Ba₂Ca₃Cu₄O₁₂–δ, on superconductivity parameters is demonstrated. If antiferromagnetism and charge stripes have some role in bringing about superconductivity at a particular temperature, the doping of nonmagnetic Zn impurity would destroy it and hence the superconductivity. However we have observed enhanced superconducting properties with the increase of Zn doping in Cu₀.₅Tl₀.₅Ba₂Ca₃Cu₄O₁₂–δ superconductor. The decreased c-axis length with the increase of Zn doping improves interlayer coupling and hence the three-dimensional conductivity in the unit cell. The role of charge carriers in CuO₂ planes of Cu₀.₅Tl₀.₅Ba₂Ca₃Cu₄O₁₂–δ in bringing about superconductivity has also been explained.
