|Title:||EXAFS studies of electron-doped nd(1.82-z)m(z)ce(0.18)cuo(y) - m=ba, sr or ca, z-less-than-or-equal-to-0.18|
|Publisher:||ELSEVIER SCIENCE BV|
|Abstract:||We describe EXAFS studies of electron-doped superconductors based on neodymium cuprate doped with cerium. The mechanism for observed changes in the transition temperature on co-doping with divalent cations is investigated using measurements of the Nd, Cu, Ce, Ba, Ca and Sr absorption edges. Changes in the close-neighbour cation-oxygen distances and the Debye-Waller factors are reported and correlated with the observed changes in T-c.|
