STUDY OF ELECTRONIC-STRUCTURE IN SINGLE TL-O SHEET SUPERCONDUCTORS BY EELS

Conference item

O 1s absorption spectra for a series of metal oxide samples based on a common structure unit (Tl,A)(Ca,Y)Sr2Cu2O 7- delta(A=Pb,V) have been measured using high energy electron energy loss spectroscopy. The pre-edge feature contains transition from the O 1s core level to the states both in the Cu-O2 sheets, which can be correlated to the transition temperature, and to states in Tl(A)-O square planner sheets. Preliminary vanadium 2p spectroscopy suggests that V occupies a well defined atomic site.
