| 中文摘要 | Two kinds of Nd1+xBa2-xCu3O7-delta, the sintered samples and zone melted samples, were treated in pure Ar at 950degreesC. The substitution of Nd ions for Ba ions in the Nd1+xBa2-xCu3O7-delta before and after the heat treatment was investigated by XRD. In order to know the effects of heat treatment, the T-c and J(c) of samples with and without the heat treatment in Ar were comparatively studied. The results show that the substitution of Nd for Ba decreases, whereas T-c and J(c) increase after the treatment. The Nd1+xBa1-xCu3O7-delta samples were oxygenated in pure oxygen at 300degreesC. Based on the XRD spectra it was found that the samples with x < 0.4 can transform from tetragonal phase into orthorhombic phase after the oxygenation, whereas in the sample with x > 0.4 no phase transition occurs even after a long time oxygenation. |
