Unusual band renormalization in the simplest iron based superconductor
J. Maletz, V. B. Zabolotnyy, D. V. Evtushinsky +9
The electronic structure of the iron chalcogenide superconductor FeSe_{1-x} was investigated by high- resolution angle-resolved photoemission spectroscopy (ARPES). The results were…
Scaling between magnetic and lattice fluctuations in iron-pnictide superconductors
R. M. Fernandes, A. E. Böhmer, C. Meingast +1
The phase diagram of the iron arsenides is dominated by a magnetic and a structural phase transition, which need to be suppressed in order for superconductivity to appear. The prox…
Nematic susceptibility of hole- and electron-doped BaFe2As2 iron-based superconductors from shear modulus measurements
A. E. Böhmer, P. Burger, F. Hardy +6
The nematic susceptibility of hole-doped Ba1-xKxFe2As2 and electron-doped Ba(Fe1-xCox)2As2 iron-based superconductors is obtained from measurements of the elastic shear modulus usi…
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…
Strong Pauli-limiting behavior of and uniaxial pressure dependencies in KFe2As2
P. Burger, F. Hardy, D. Aoki +8
KFe2As2 single crystals are studied using specific-heat, high-resolution thermal-expansion, magnetization, and magnetostriction measurements. The magnetization and magnetostriction…
Evidence of Strong Correlations and Coherence-Incoherence Crossover in the Iron Pnictide Superconductor KFe2As2
F. Hardy, A. E. Boehmer, D. Aoki +9
Using resistivity, heat-capacity, thermal-expansion, and susceptibility measurements we study the normal-state behavior of KFe2As2. We find that both the Sommerfeld coefficient gam…
