Abstract

An analysis of the temperature dependence of the upper critical field in several cuprate families leads to the conclusion that magnetic impurities are present even in samples with the maximum observed value of T_c. A new parameter, 'intrinsic' T_c which is its value in the absence of magnetic impurities, is introduced. The maximum value of 'intrinsic' T_c which corresponds to the maximum doping level, appears to be similar for different cuprates and to be equal to 160-170K. THis is an upper limit of T_c in the cuprates.
