| dc.description.abstractEn | We report the effect of oxygen-annealing in the superconductivity and electronic states for the Mo0.3Cu0.7Sr2YCu2O y compound. The influence of oxygen annealing in the electronic states for Mo0.3Cu0.7Sr2YCu2O y associated with a nonsuperconducting to superconducting state transformation has been investigated by means of X-ray photoelectron spectroscopy, powder X-ray diffraction, magnetic susceptibility, and resistivity measurements. We unambiguously show the preeminence of the MoV state over the MoVI one; annealing under an oxygen atmosphere enhances both the MoVI and CuII amounts. The enhancement of MoVI after oxygen annealing is in close relation with the decrease in the O 2p→Cu 3d charge-transfer energy resulting in superconducting properties. Oxygen annealing is then seemed to reduce the copper plane hole concentration of the overdoped as-prepared sample, which induces superconductivity in the Cu-O planes. | |
