Unusual temperature evolution of superconductivity in LiFeAs
P. K. Nag, R. Schlegel, D. Baumann +5
We have performed temperature dependent tunneling spectroscopy on an impurity-free surface area of a LiFeAs single crystal. Our data reveal a highly unusual temperature evolution o…
Spatial competition of the ground states in 1111 iron pnictides
G. Lang, L. Veyrat, U. Graefe +5
Using nuclear quadrupole resonance, the phase diagram of 1111 FeAsOF (La, Ce, Sm) iron pnictides is constructed as a function of the local charge distribution…
Acoustic signatures of the phases and phase transitions in YbTiO
Subhro Bhattacharjee, S. Erfanifam, E. L. Green +11
We report on measurements of the sound velocity and attenuation in a single crystal of the candidate quantum- spin-ice material YbTiO as a function of temperature and m…
Non-Fermi-liquid scattering rates and anomalous band dispersion in ferropnictides
J. Fink, A. Charnukha, E. D. L. Rienks +13
Angle-resolved photoemission spectroscopy (ARPES) is used to study the band dispersion and the quasiparticle scattering rates in two ferropnictides systems. Our ARPES results show…
