We analyze the competition between high-temperature superconductivity (SC) and antiferromagnetism (AF) using the extended Hubbard model containing following matrix elements in the Hamiltonian: Hund's on-site field F H , singlesite Coulomb repulsion U ¼ ði; ij1=rji; iÞ; two-site charge-charge, exchan
