Electron Spin Pairing in High-T_c Superconductors

An electron pairing theory based on effective electron spin coupling mediated by antiferromagnetically correlated local moments is presented to account for high-T_c phenomena. We show that Kondo scattering and the suppression of the antiferromagnetic superexchange between Cu²⁺ moments lead to local triplet pairing, the mechanism underlying high-T_c superconductivity.
