摘要：

Motion of magnetic flux in a ring-shaped quench-and-melt-grown YBa2Cu3O7 sample has been studied using several search coils coaxially set on a surface of the ring. It is shown that the flux does not obey the critical state model but moves freely under the Lorentz force induced by external pulsed magnetic field.
