Abstract
We describe EXAFS studies of electron-doped superconductors based on n eodymium cuprate doped with cerium. The mechanism for observed changes in the transition temperature on co-doping with divalent cations is i nvestigated using measurements of the Nd, Cu, Ce, Ba, Ca and Sr absorp tion edges. Changes in the close-neighbour cation-oxygen distances and the Debye-Waller factors are reported and correlated with the observe d changes in T-c.
