Phys. Rev. Lett. 62, 214–216 (1989)Scanning-Tunneling-Microscope Observation of the Abrikosov Flux Lattice and the Density of States near and inside a FluxoidReceived 28 October 1988; published in the issue dated 9 January 1989 The Abrikosov flux lattice is imaged in NbSe2 by tunneling into the superconducting gap edge with a low-temperature scanning-tunneling microscope. The tunneling conductance into a single vortex core is strongly peaked at the Fermi energy, suggesting the existence of core states or core excitations. As one moves away from the core, this feature evolves into a density of states which is consistent with a BCS superconducting gap. © 1989 The American Physical Society URL:
