Effect of exchange on spin-polaron behavior in the Emery model
Abstract
The paper examines the effect of exchange interaction on the behavior of a hole on oxygen in the Emery model of a high-temperature superconductor. It is shown that the spin state produced by the hole can be a purely ferromagnetic polaron only up to a certain (small) energy-normalized jump of the critical value of the exchange constant.
