Hj. Hug et al., OBSERVATION AND MANIPULATION OF VORTICES IN A YBA2CU3O7 THIN-FILM WITH A LOW-TEMPERATURE MAGNETIC FORCE MICROSCOPE, Physica. C, Superconductivity, 235, 1994, pp. 2695-2696
A low temperature magnetic force microscope has been applied to spatia
lly resolve single vortices in an epitaxially grown YBa2Cu3O7 thin fil
m at 77 K. A disordered vortex arrangement is observed. Further the ma
gnetic stray field of the magnetic force microscope tip is used to loc
ally nucleate vortex bundles.
