A low temperature magnetic force microscope has been applied to spatially resolve single vortices in an epitaxially grown YBa2Cu3O7-δ thin film at 77 K. A disordered vortex arrangement is observed, and the vortices are strongly pinned. The observed phase is expected to be truly superconducting due to strong pinning.
