| Popis: | Sr2CuO2Cl2. represents a nearly ideal case of a 2-D antiferromagnetic CuO2-plane and thus is of particular interest in the context of the origins of high TC superconductivity. We present high energy spectroscopic results on single crystalline Sr2CuO2Cl2. Using electron-energy loss spectroscopy in transmission we have measured the loss function along the high symmetry directions in the CuO2-plane. X-ray photoemission spectroscopy is applied to study the valence band and the Cu 2p spectrum. Comparison of the experiment to a cluster calculation is given. |
