摘要：
The influence of oxygen doping on the superconducting properties of HgBa2CuO4+delta is studied. Ac and de magnetization measurements on well defined samples (delta approximate to 0.01 - 0.09) are performed. These measurements as a function of temperature show a parabolic-like behaviour of T-c(delta). Analyzing the magnetization curves at T = 5 K yields an estimation of H-c1. The results show a reduction of H-c1 with decreasing oxygen content.
