Contribution of the non-Heisenberg ring exchange to the magnetic mechanism of high-Tc superconductivity

Abstract:
The effect of non-Heisenberg four-spin ring exchange on the superconducting transition temperature in strongly correlated electron systems is studied. It is shown that the ring exchange can significantly suppress the contribution of the Heisenberg exchange to superconducting pairing.
