Nematic state of the FeSe superconductor
Sahana Rößler, Mauro Coduri, Alexander A. Tsirlin +8
We study the crystal structure of the tetragonal iron selenide FeSe and its nematic phase transition to the low-temperature orthorhombic structure using synchrotron x-ray and neutr…
Influence of disorder on the signature of pseudogap and multigap superconducting behavior in FeSe
Sahana Rößler, Chien-Lung Huang, Lin Jiao +3
We investigated several FeSe single crystals grown by two different methods by utilizing experimental techniques namely, resistivity, magnetoresistance, specific heat, scanning tun…
Pressure-induced ferromagnetism due to an anisotropic electronic topological transition in Fe1.08Te
K. Mydeen, D. Kasinathan, C. Koz +8
A rapid and anisotropic modification of the Fermi-surface shape can be associated with abrupt changes in crystalline lattice geometry or in the magnetic state of a material. In thi…
Impurity-induced bound states inside the superconducting gap of FeSe
Lin Jiao, Sahana Rößler, Cevriye Koz +4
We investigate the local density of states in the vicinity of a native dumbbell defect arising from an Fe vacancy in FeSe single crystals. The tunneling spectra close to the impuri…
Homogeneity range of ternary 11-type chalcogenides FeTeSe
Cevriye Koz, Sahana Rößler, Steffen Wirth +1
The 11-type Fe-chalcogenides belong to the family of Fe-based superconductors. In these compounds, the interstitial Fe is known to strongly influence the magnetic and superconducti…
Synthesis, phase stability, structural and physical properties of 11-type iron chalcogenides
Sahana Rößler, Cevriye Koz, Steffen Wirth +1
This article reviews recent experimental investigations on two binary Fe-chalcogenides: FeSe and FeTe. The main focus is on synthesis, single crystal growth, chemical compo…
