Absence of hexagonal to square structural transition in LiFeAs vortex matter
Sven Hoffmann, Ronny Schlegel, Christian Salazar +9
We investigated magnetic vortices in two stoichiometric LiFeAs samples by means of scanning tunneling microscopy and spectroscopy. The vortices were revealed by measuring the local…
Defect states in LiFeAs as seen by low temperature scanning tunneling microscopy and spectroscopy
R. Schlegel, P. K. Nag, D. Baumann +4
We present a microscopic investigation of frequently observed impurity-induced states in stoichiometric LiFeAs using low temperature scanning tunneling microscopy and spectroscopy…
Unusual temperature evolution of superconductivity in LiFeAs
P. K. Nag, R. Schlegel, D. Baumann +5
We have performed temperature dependent tunneling spectroscopy on an impurity-free surface area of a LiFeAs single crystal. Our data reveal a highly unusual temperature evolution o…
Structural study of monolayer cobalt phthalocyanine adsorbed on graphite
M. Scheffler, L. Smykalla, D. Baumann +6
We present microscopic investigations on the two-dimensional arrangement of cobalt phthalocyanine molecules on a graphite (HOPG) substrate in the low coverage regime. The initial g…
Interband Quasiparticle Scattering in Superconducting LiFeAs Reconciles Photoemission and Tunneling Measurements
Christian Hess, Steffen Sykora, Torben Hänke +7
Several angle resolved photoemission spectroscopy (ARPES) studies reveal a poorly nested Fermi surface of LiFeAs, far away from a spin density wave instability, and clear-cut super…
Probing the Unconventional Superconducting State of LiFeAs by Quasiparticle Interference
T. Hänke, S. Sykora, R. Schlegel +7
A crucial step in revealing the nature of unconventional superconductivity is to investigate the symmetry of the superconducting order parameter. Scanning tunneling spectroscopy ha…
