Sr2CuO2Cl2. Signifies an almost perfect case of a 2-D antiferromagnetic CuO2-plane and so is of distinct fascination while in the context in the origins of large TC superconductivity. We use The only-web-site impurity Anderson design with five Cu 3d orbitals and O 2p valence bands specified with the irreducible representations https://okada4dsg.com/
