Abstract

We have studied the relationship between the oxygen content and superconducting properties for a series of Nd_1+xBa_2-xCu₃O_7-δ (0 ≤ x ≤ 0.4) solid solution. The temperature variation of oxygen content was studied as a function of x by means of both TG-DTA and chemical compositional analyses. The amount of oxygen absorbed during oxygen annealing was found to decrease with an increasing Nd content. In the sample with x = 0, the superconductivity transition temperature T_c increased monotonically with a decrease in the annealing temperature T_a, while T_c for the samples with larger x values showed non-monotonic T_a dependence. The T_a value required to achieve the highest T_c was higher than that for the largest x. On the other hand, the pinning properties improved with a decrease in T_a.
