Description
The top seed method and the interior seed method are com-bined for the purpose of improving the electromagnetism of the superconductor by removing defects such as processing and cracks in the YBaCuO crystal. The top seed melt growth process is widely used as a process for growing superconducting bulk.When measuring the magnetic levitation force on the upper surface of YBCO superconductor, the YBCO superconductor fabricated by Top + Interior seeding process was observed at 66.787N. In the case of the YBCO superconductor fabricated with the Interior seeding process, it was observed at an average of 37.387N. In the YBCO superconductor fabricated using the Top + Interior seeding method, the growth surface of the superconducting bulk upper seed and the part where the growth surface of the seed touches from the center are generated, so from the measurement result of the YBCO superconductor fabricated by the Interior seeding processIt is also confirmed that it is high. The Top + Interior seeding process proves to be a very effective way to complement the disadvantages of the Interior seeding process displayed on the top surface of the YBCO superconducting bulk.This research was supported by the Korean Electric Power Corporation [Grant number:R16XA01].
