Abstract

The damping of the oscillations of a small permanent magnet (spherical shape, radius 0.1 mm) levitating between two parallel epitaxial YBCO films is measured as a function of oscillation amplitude and temperature. At small amplitudes the dissipation is found to be orders of magnitude lower than in bulk YBCO, Q-factors exceeding one million at low temperatures. With increasing amplitude the ...
