Detecting flux creep in superconducting YBCO thin films via damping of the oscillations of a levitating permanent magnet

R. Grosser, A. Martin, M. Niemetz +2

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 oscil…
