X-Ray Irradiation of YBa 2 Cu 3 O y

The effects of irradiation, synchrotron radiation (8 k=30 keV), of high- T C superconductor YBa 2 Cu 3 O y have been studied by the Meissner effect and X-ray photoelectron spectroscopy measurements. Changes in the Cu2p satellite emission indicate that Cu 2+ changes to Cu 1+ with irradiation. Althoug...

Description
Summary:The effects of irradiation, synchrotron radiation (8 k=30 keV), of high- T C superconductor YBa 2 Cu 3 O y have been studied by the Meissner effect and X-ray photoelectron spectroscopy measurements. Changes in the Cu2p satellite emission indicate that Cu 2+ changes to Cu 1+ with irradiation. Although diamagnetic signals decreased with the irradiation of intense synchrotron radiation, no significant change in the T C was observed.
