Fermi surface evolution in Weyl semimetal t-PtBi probed by transverse transport properties
F. Caglieris, M. Ceccardi, D. Efremov +8
The combination of non-trivial topology and superconductivity opens to novel quantum devices. The discovery of intrinsic materials where such properties appear together represents…
Fermi arcs dominating the electronic surface properties of trigonal PtBi
Sven Hoffmann, Sebastian Schimmel, Riccardo Vocaturo +10
Materials combining topologically non-trivial behavior and superconductivity offer a potential route for quantum computation. However, the set of available materials intrinsically…
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…
Revisiting the phase diagram of LaFeCoAsO on single crystals by thermodynamic methods
Francesco Scaravaggi, Sven Sauerland, Liran Wang +13
In this work we revisit the phase diagram of Co-doped LaFeAsO using single crystals and thermodynamic methods. From magnetic susceptibility studies we track the doping evolution of…
Berezinskii-Kosterlitz-Thouless transition in the type-I Weyl semimetal PtBi
Arthur Veyrat, Valentin Labracherie, Dima L. Bashlakov +12
Symmetry breaking in topological matter has become in recent years a key concept in condensed matter physics to unveil novel electronic states. In this work, we predict that broken…
Evolution of the nematic susceptibility in LaFeCoAsO
Xiaochen Hong, Federico Caglieris, Rhea Kappenberger +8
The identification of electronic nematicity across series of iron-based superconductors raises the question of its relationship with superconductivity and other ordered states. Her…
Strain-derivative of thermoelectric properties: a sensitive probe for nematicity
Federico Caglieris, Christoph Wuttke, Xiaochen Hong +6
The nematic instability of iron-based superconductors is an undebatable ingredient of the physics of iron-based superconductors. Yet, its origin remains enigmatic as it involves a…
Quantized charge transport in chiral Majorana edge modes
Stephan Rachel, Eric Mascot, Sagen Cocklin +2
Majorana fermions can be realized as quasiparticles in topological superconductors, with potential applications in topological quantum computing. Recently, lattices of magnetic ada…
Nematicity in LaFeAsOF
C. Hess, H. Grafe, A. Kondrat +6
Orbital ordering has recently emerged as another important state in iron based superconductors, and its role for superconductivity as well as its connection to magnetic order and o…
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…
Combined resistivity and Hall effect study on NaFeRhAs single crystals
Frank Steckel, Robert Beck, Maria Roslova +5
Electrical transport measurements are used to study the Rh-doped NaFeAs superconductor series with a focus on the tetragonal phase. The resistivity curvature has an anomalous tempe…
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…
Crystal growth and the electronic phase diagram of the 4 doped NaFeRhAs in comparison with 3 doped NaFeCoAs
Frank Steckel, Maria Roslova, Robert Beck +13
Single crystals of NaFeTAs with T = Co, Rh have been grown using a self-flux technique. The crystals were thoroughly characterized by powder X-ray diffraction,…
