The phonon model of the high‐temperature superconductors is considered, taking into account the quasi‐two‐dimensional spectrum of carriers. The influence of paramagnetic impurities on the dependence of T c on pressure, as well as on the value of jumps of the electron heat capacity and thermal expansion, is analyzed.
