高温超電導体の段差境界配置におけるピンニング特性

抄録

In this research, we investigated the characteristic change of the magnetic flux pinning phenomenon caused by creating a step between three high-temperature superconductors. In order to investigate the characteristics, we created a levitation system that uses the superconducting pinning effect on the levitation body created by the magnetic flux concentration method. By analyzing the restoring force characteristics of the created levitation system, we verified how the restoration characteristics change depending on the step. As a result of the experiment, the restoring force was improved when the magnetic flux focusing part and the step of HTS were under specific conditions. From this, Experiments have revealed the usefulness of creating steps between superconductors.
