• A major problem associated with superconducting magnetic bearings is the damping of vibration. A demonstration is given of the use of a dissipation peak due to flux line movement in YBa_2Cu_3O_<7-x> to provide temperature-dependent damping of vibration of a mechanical oscillator. Scaling of the present results shows that it is possible to decrease the resonance Q of a 1 kg oscillator to 10 with just 0.02 kg of melt-processed YBa_2Cu_3O_<7-x>. The proposed superconducting damper is distinct from the levitation superconductor in the magnetic bearing.
