Abstract: The paper presents the experimental results showing a specific
behavior of high-temperature superconductors in various electric circuits.
Self-oscillations of temperature and current in the superconductor manifest
themselves as sharp peaks of voltage across the superconductor on the
background of a basic signal. It is shown that these oscillations can also
appear when a superconductor is in flux creep regime. In inhomogeneous
superconducting samples, the oscillations are associated with cyclic movement
of normal or resistive zones.
Keywords: high temperature superconductor, self-oscillation, superconducting thin film
