ELECTRONIC-SPECTRUM AND CRITICAL-TEMPERAT URE OF THE HTSC WITH SEVERAL CUPRATE LAYERS IN A CELL

Basing on the model microscopic Lagrangian of a multilayered system of fermi-particles with attraction, the equations for superconducting ga ps, critical temperature T-c and chemical potential have been obtained for arbitrary carrier density and number of layers in the multilayere s metal. Cooper pairs coexist with local ones,. which leads to a non-u niform growth of T-c of the multilayered conductor studied, for exampl e, in the bilayered compaund YBa2Cu3O6+delta with changing delta.
