Scanning Tunneling Microscopy/Spectroscopy of Vortices in LiFeAs

open access: yes, 2012
We investigate vortices in LiFeAs using scanning tunneling microscopy/spectroscopy. Zero-field tunneling spectra show two superconducting gaps without detectable spectral weight near the Fermi energy, evidencing fully-gapped multi-band superconductivity.
