Abstract

The vortex lattice in clean 2H-NbSe₂ is investigated by STM at 4.2 K. The experimental results predominantly address three major issues of current importance. (1) Sufficiently large in-plane transport currents through the superconducting sample cause the motion of vortices, which can directly be detected. (2) The apparent vortex diameter is about twice that expected from elementary theory. A pronounced shrinking of the vortex core with increasing external magnetic field is observed. (3) The STM results combined with some elementary magnetostatic model calculations shed some light on the difficulties encountered in the imaging of flux line lattices by magnetic force microscopy.
