چکیده انگلیسی
The temperature dependence of the magnetic levitation force has been investigated for single-grain YBCO bulk sample, 20Â mm in diameter with a thickness of 8Â mm, fabricated by top-seeded melt growth (TSMG) method using Nd123 seeded. The superconducting properties of the single grain YBCO bulk are studied by VSM (Vibrating Sample Magnetometer), the microstructures and the phase constituents of those that are seen by SEM (Scanning Electron Microscope) and XRD (X-ray Diffraction). The measurements of superconducting properties indicated that magnetic levitation forces of the sample were found 11.23, 10.81, 10.34, 9.23 and 7.02Â NÂ at the temperatures of 37, 47, 57, 67 and 77, respectively, and the values of the onset critical temperature (Tc) and the zero-field critical current density (Jc) are 89.3Â K and 5.6Â ÃÂ 104 A/cm2 at 77Â K, respectively. This research is intended to help for the large scale superconductor levitation performances at different temperatures.
