Yg. Zhao et al., EFFECT OF ZN DOPING ON T(C) OF Y1-XPRXBA2CU3-YZNYOZ AND ITS DEPENDENCE ON PR DOPING, Physica. C, Superconductivity, 209(4), 1993, pp. 472-476
The effect of Zn doping on T(c) of Y1-xPrxBa2Cu3-yZnyOz (x=0, 0.1, 0.2
, 0.3) was investigated. For the x=0 system, T(c) decreases linearly w
ith the Zn real doping amount, which was determined by EDAX. This line
ar behaviour also holds for the other three systems with x = 0.1, 0.2,
0.3. These results were qualitatively explained by using the Abrikoso
v-Gor'kov pair-breaking theory. The slope of the dT(c)/dy increases wi
th Pr doping, which indicated the dependence of the pair-breaking effe
ct on carrier density.
