Sr2CuO2Cl2. signifies a virtually suitable circumstance of the two-D antiferromagnetic CuO2-aircraft and therefore is of certain interest during the context of the origins of superior TC superconductivity. We now 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/
