Anomalous field evolution of the mixed-state linewidth in the second superconducting dome of LaFeAsO ()
Rustem Khasanov, Pierre Dalmas de Réotier, Samuele Sanna +9
We report a transverse-field muon-spin rotation/relaxation (SR) study of the internal-field distribution in the mixed state of LaFeAsOF and LaFeAsOH$_…
Nematicity in LaFeAsO single crystals studied by elastoresistance, high-resolution thermal expansion and shear-modulus measurements
X. C. Hong, S. Sauerland, L. Wang +10
Nematicity in LaFeAsO single crystals is studied by means of high-resolution thermal expansion, shear modulus, and elastoresistivity measurements. A softening of the shear modulus…
Strong surface termination dependence of the electronic structure of polar superconductor LaFeAsO revealed by nano-ARPES
