Description
The compensation doped system Nd(1+x)-cCAcBa2-x Cu3Oy and Nd1+xBa2-xCu3-zZnzOy are studied to elucidate both the dependence of Tc on the Cu - O plane hole concentration and the effect of disorder on the planes. Nd substitution for Ba reduces Tc and the plane holes. The study is discussed in this paper. Ca substitution compensates for Nd, raising Tc and the plane holes. Zn has a small effect on the hole concentration. More importantly, Zn causes disorder on the Cu-O plane, suppressing Tc. The choice of these Nd systems is very important, because contrary to the YBa2Cu3-xAnxOy based systems, the Hall number can be unambiguously interpreted and is in agreement with the plane hole concentration derived from chemical analysis and the method of Tokura et al. for dividing the total holes into mobile plane holes and local chain holes
