Sr2CuO2Cl2. signifies a virtually suitable situation of a two-D antiferromagnetic CuO2-airplane and so is of unique curiosity inside the context in the origins of superior TC superconductivity. We use The only-internet site impurity Anderson model with 5 Cu 3d orbitals and O 2p valence bands specified by the irreducible representations https://okada4dsg.com/
