| Abstract: | Preparation of single-phase and multiphase Y-Ba-Cu-O system superconductors are presented. X-ray diffraction patterns and high resolution electron microscopy showed that the samples with a nominal composition Y: Ba:Cu=1:2:3 can be single phase and their structure are orthorhombically distorted perovskite. Samples of other composition are multiphase.
The superconductivity of the sample is detected by four-probe resistance and AC susceptibility measurement. The zero resistance temperatures are around 90K. |
