• Damping properties in superconducting levitation have been investigated using melt-processed YBaCuO bulk superconductors. The damping of superconducting levitation is so small that additional noncontact dampers are required for practical use of superconducting levitation. Eddy current dampers and superconducting dampers of sintered YBaCuO materials have been proposed and studied as additional noncontact dampers. The damping coefficient has been improved about 20-fold by combining a copper damper with superconducting levitation, and further enhancement can be expected.
