Description

Detailed studies were carried out on resistivity transport behaviour and superconducting transition temperature in various excess oxygen-doped La1.85Sr0.15CuO4+δ and La1.85Ba0.15CuO4+δ systems. It indicates that, with decrease of oxygen content, the distribution of excess oxygen undergoes a gradual transition from ordering to disordering. The related physics in these two systems was discussed on the basis of competition between two behaviours of Sr and Ba disordering potential scattering and excess oxygen cooperative ordering
