摘要: The effect of antiferromagnetic order suppression and charge stripes formation by Zn3d10 (S=0) substitution at Cu3d9 (S=1∕2) sites in CuO2 planes Cu0.5Tl0.5Ba2Ca3Cu4O12−δ on the superconductivity parameters is demonstrated. If antiferromagnetism have some role bringing about a particular temperature, doping with nonmagnetic Zn impurity would destroy it hence superconductivity. However we observed enhanced superconducting properties increased superconductor. decreased c-axis length improves interlayer coupling three-dimensional conductivity unit cell. carriers Cu0.5Tl0.5Ba2Ca3Cu4−yZnyO12−δ has also been explained.
