Single Crystal Structure Determination of YBa2Cu3-χFeχO7-y

X-ray single crystal structure determination was performed on YBa2Cu3-xFexO7-y with nominal I = 0.05 and x = 0.22. The results showed that Fe atoms solely went into the Cu(2) sites. Electron density mapping also indicated the non-localisation of the oxygen electrons in the Cu(1) plane.
