Ultra-short time local current density distribution in superconducting strips: A new experimental approach

We have studied the local current distribution in thin superconducting strips in the presence of a transverse magnetic field, at very short times (approximately 10 μs) after the establishment of the critical state. We used a non-conventional technique that combines the use of a pulsed magnetic field...
