Sr2CuO2Cl2. Represents an almost suitable case of the two-D antiferromagnetic CuO2-aircraft and therefore is of specific curiosity during the context of the origins of large TC superconductivity. Now we have measured experimentally and analyzed theoretically the Ti 2p X-ray photoemission spectra (XPS) along with the resonant enhancement of valence photoemissionat https://okada4dsg.com/
