Institute for Single Crystals, STC"Institute for Single Crystals", National Academy of Sciences of Ukraine, 60 Lenin Ave., 61001 Kharkiv, Ukraine
The properties of internal (chemical) pressure Pi in superconducting YBa2Cu3O7-y perovskite are analytically investigated. Predicted are the values of the critical temperature Tc for the main crystallographic axes, the change of the value of dTc/dPi and the possibility to obtain YBa2Cu3O7-y samples with Tc = 166.7 K.
