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…
Structural and electronic phase diagrams of CeFeAsO1-xFx and SmFeAsO1-xFx
Hemke Maeter, Jorge Enrique Hamann Borrero, Til Goltz +17
We have studied the structural and electronic phase diagrams of CeFeAsO1-xFx and SmFeAsO1-xFx by a detailed analysis of muon spin relaxation experiments, synchrotron X-ray diffract…
High-field electron spin resonance spectroscopy study of GdOFFeAs superconductors
A. Alfonsov, F. Murányi, V. Kataev +16
We report a detailed investigation of GdOFFeAs (x = 0, 0.07 and 0.14) samples by means of high-field/high-frequency electron spin resonance (HF-ESR) together with mea…
Scaling of normal-state transport properties of 1111 iron-pnictide superconductors
E. Arushanov, C. Hess, G. Behr +6
We show that the zero field normal-state resistivity above Tc for various levels of electron doping-both for underdoped, optimally, and overdoped LaO1-xFxFeAs, i.e. (x=0.05-0.075 a…
Unusual Nernst effect and spin density wave precursors in superconducting
Agnieszka Kondrat, Günter Behr, Bernd Büchner +1
The Nernst effect has recently proven as a sensitive probe for detecting unusual normal state properties of unconventional superconductors. Here we present a systematic study of th…
Thermal expansion of LaFeAsO: Evidence for high-temperature fluctuations
L. Wang, U. Kohler, N. Leps +8
We present measurements of the thermal expansion coefficient alpha of polycrystalline LaFeAsO1-xFx (x <= 0.1). The magnetic and structural transitions of the samples with x <= 0.04…
