Superconducting and Electromagnetic Properties of YBaCuO Using Effective Melt Growth Process

Abstract

The interior seed melting growth (ISMG) method was applied to overcome the shortcomings of the seeded melt growth. According to the results of measuring captured magnetic force at 77 K, the interior side showed a higher captured magnetic force at 2.27 kG the top side at 2.08 kG. The combination of the top seed method and the interior seed method could improve both the magnetic levitation force and the captured magnetic force of both the interior and top sides. When the bulk samples were compared before and after neutron irradiation, the bulk samples after irradiation showed relatively improved material properties when compared to those before irradiation. To measure changes in other material properties by ab/ab + ac sector in YBaCuO bulk single crystal growth, superconducting properties were measured by varying the ab area size area, and when seeding was changed in a vertical direction, higher to measure different property changes in ab/ab + ac sector, it could obtain high magnetic levitation force and captured magnetic force. This result seems to because the ab area with high superconducting properties showed a relatively larger growth.
