In this research, we investigated the characteristic change of the restoring force caused by arranging two hightemperature superconductors (HTS) with concave step. In order to investigate the characteristics, we created a superconducting magnetic bearing with a structure that uses the side surfaces of the HTS for pinning.
By analyzing the restoring force characteristics of the created bearing in each direction, we verified whether the restoring force characteristics would change. As a result of the experiment, it was confirmed the spring constant of restoring force in each direction is increased by arranging the superconductor with a shape of concave step. Also, comparing it with the gap arrangements it was found that it provides greater the spring constant. Therefore, it was found that the restoring force characteristics was improved by adding steps to the high-temperature superconductor. Experiments have shown the usefulness of applying a concave step arrangement to superconductors.
