Abstract:
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 and a synchronized pulsed laser. The high energy laser spot was directed to irradiate different regions of the sample at controlled delays after the rising/falling edge of the magnetic field. The time integrated photovoltaic pulse (approximately 10 ns) related to flux redistribution was studied and a model is proposed that describes the measured signal in terms of the local critical current distribution present in the sample at the time of laser irradiation.
