|Abstract:||Computer simulation techniques have been used to study the structural changes caused by Zn, Ce, Pr, Th, Ca, Sr, Fe, Co, and Ni doping in YBa2Cu4O8. We found that benefical dopants (Ca and Sr) and deleterious dopants (Pr, Th, Zn, Ce, Fe, Co and Ni) caused very different structural changes in Cu(2)O(1), Cu(1)O(4′), z(Ba)Z(O(1)), Cu(2)O(2) and Cu(2)O(3). It appears that Ca-doped YBa2Cu4O8 is under "positive chemical pressure" while YBa2Cu4O8 doped with deleterious dopants behaves as if it is under "negative chemical pressure". © 1995.|
