Abstract
We study numerically the hole pairing induced by spin-wave exchange. The contact hole-hole interaction is taken into account as well. Consideration is given to the assumption of preservation of antiferromagnetic order at all relevant pairing scales. The strongest pairing is obtained for the d-wave symmetry of the gap. Dependence of the value of the gap on hole concentration and temperature is presented. For the critical temperature we obtain Tc∼100 K at the hole concentration δ∼0.2–0.3.
