摘要
We calculate the current distribution present in superconducting planar thin films of different geometries including strips with slits, pi/2-turns, and widenings. We consider simultaneous application of external transport electric current and perpendicular magnetic field and systematically obtain the current distribution. From the calculations we show how, based on different sequences of the externally applied magnitudes, one can control the current distribution in the thin sample.
