Abstract:
The fine structures of the oxygen K-edge in the Y-Ba-Cu-O system, in which hole content was controlled by reducing the oxygen content and doping elements (La, Ca and Co), were investigated by electron energy loss spectroscopy (EELS). When Ba(+2) and Y(+3) were replaced by La(+3) and Ca(+2), respectively, the oxygen content of the sample changed and the peak corresponding to the hole state near the Fermi energy sensitively changed with the average hole content. When Cu(+2) was replaced by Co(+3), T c decreased drastically and the peak at the oxygen K-edge shifted to higher energy.
