Abstract

Amendments to the exchange interaction can alter the superconducting transition temperature, so on the basis of numerical self-consistent solution of two equations in the framework of the t-J model, we investigate the influence of the four spin exchange on the concentration dependence of the transition temperature to the superconducting phase with d(x2−y2) - the type of symmetry of the order.
