Phase diagram of high-temperature superconductors
Abstract
Based on an analysis of experimental data on phase transitions in high-Tc superconductors, particularly La(2-x)Sr(x)CuO4 and YBa2Cu3O(7-y), phase diagrams are plotted for this class of compounds in (T; x), (T; y) variables. A large number of coexisting phases are identified in these systems, some of them magnetically ordered (with antiferromagnetic long-range order) and some superconducting. The critical temperature is found to depend substantially on (x; y) parameters.
