Quantum criticality in AFe2As2 with A = K, Rb, and Cs suppresses superconductivity
Felix Eilers, Kai Grube, Diego A. Zocco +10
Superconductors close to quantum phase transitions often exhibit a simultaneous increase of electronic correlations and superconducting transition temperatures. Typical examples ar…
Fermi Surface of KFeAs from Quantum Oscillations in Magnetostriction
D. A. Zocco, K. Grube, F. Eilers +2
We present a study of the Fermi surface of KFeAs single crystals. Quantum oscillations were observed in magnetostriction measured down to 50 mK and in magnetic fields u…
Pauli-Limited Multiband Superconductivity in KFe2As2
D. A. Zocco, K. Grube, F. Eilers +2
The upper critical field Hc2(T) of the multiband superconductor KFe2As2 has been studied via low-temperature thermal expansion and magnetostriction measurements. We present compell…
Lack of coupling between superconductivity and orthorhombic distortion in stoichiometric single-crystalline FeSe
A. E. Böhmer, F. Hardy, F. Eilers +5
The coupling between superconductivity and othorhombic distortion is studied in vapor-grown FeSe single crystals using high-resolution thermal-expansion measurements. In contrast t…
Electronic structure of single-crystalline Sr(FeCo)As probed by x-ray absorption spectroscopy: Evidence for isovalent substitution of Fe by Co
M. Merz, F. Eilers, Th. Wolf +3
The substitutional dependence of valence and spin-state configurations of Sr(FeCo)As ( 0, 0.05, 0.11, 0.17, and 0.38) is investigated with near-edge x-ray…
