Abstract
We review here recent experimental investigations on the dependence of Tc on hole concentration in High Tc cuprates, La2-xSrxCuO4, YBa2Cu3Oy — like compounds and also the new comp ound Nd2-x-yCexSryCuO4. In all these compounds, the hole concentration in the sheet of Cu-O pyramids or octahedra is the major experimental variable closely correlated with Tc.

The samples prepared in ref. [2] have p above the dashed line (p=x), which may be attributed to the presence of La vacancies (∼1. 5%). It has been later noticed that these La vacancies can be much reduced by the improved method to prepare the homogeneous samples of La2-xSrxCuO4. See the paper by Takagi et al. in the Proceedings.
