Abstract

The YBCO superconductors prepared by the Melt- Powder-Melt-Growth (MPMG) process exhibit high critical current density over 30, 000A/cm² at 77K and 1T. Because these are expected to be applied to various fields such as magnetic bearing, magnetic levitation, magnetic shielding, and etc. In such applications in order to design applied high-T_c superconductors it is important that assessment methods of magnetic property should be developed. Especially, in real applications it is necessary to assess quench property of the superconductors. So we measured AC quench property of the YBCO ring specimen under the AC magnetic field with the frequency of 50Hz. We got the experimental results that the superconductor results in the quench by the heat under the some AC magnetic field, and that the quench property of ring specimen is ruled by its weak link.
