Abstract
The value of the critical temperature of the cuprates correlates with the doping level and is affected by the interplay of two competing fac tors: 1) the increase in carrier concentration, and 2) the pair-breaki ng effect of magnetic impurities. A new parameter, ''intrinsic'' T-c i s introduced. The value of T-c;intr appears to be similar for differen t cuprates and to be equal to 160-170K. This is an upper limit of T-c in the cuprates.
