'Oxygen' effect in ionization loss spectrum of Cu3p in YBa2Cu3Ox ceramics
- 1. AN SSSR, Leningrad (Russian Federation). Fiziko-Tekhnicheskij Inst.
Description
YBaCu3Ox ceramic samples with different oxygen concentration (6.2; 6.5 and 6.9) in a volume are investigated. The process of degradation of samples with high X in the vacuum is analyzed. The surface purification is performed through scribing in argon atmosphere. A new effect is ascertained which is manifested in high sensitivity of Cu3p ionization loss spectrum to the density of the non-occupied electron states at the Fermi level. It is shown that Cu3p ionization spectrum can serve as a new criterion of superconductor surface quality from the viewpoint of its electronic structure
