Abstract
A new technique has been developed to remove flux quanta trapped in superconducting film. It consists of measuring the magnetic field distribution over a superconductor with an rf SQUID and removing the detected trapped flux using laser beam scanning. The trapped flux movement follows the motion of the Ar laser beam exactly. By scanning the laser beam over the trapped flux quanta, the trapped flux is successfully moved to any desired location.Keywords
