English abstract:
Numerical simulations of the current and field distribution in thin superconducting films are carried out
for a given material law Jc(B) and as a function of the applied field H, taking the sample´s self-field into
account. The dependence of the critical current density on the applied field Jc(H) is computed for comparison
with experiment, considering the geometry of transport measurements.
We show that extrapolating the high-field power law Jc α B to the lowest fields results in a finite critical
current at zero applied field Jc(H = 0), despite the singularity of Jc(B). Moreover, particular features of
the experiment, such as a low field plateau in Jc(H), are reproduced and found to be determined by the
