Measurement of spin dynamics in a layered nickelate using x-ray photon correlation spectroscopy: Evidence for intrinsic destabilization of incommensurate stripes at low temperatures
Alessandro Ricci, Nicola Poccia, Gaetano Campi +15
We study the temporal stability of stripe-type spin order in a layered nickelate with X-ray photon correlation spectroscopy and observe fluctuations on time scales of tens of minut…
Surface adatom conductance filtering in scanning tunneling spectroscopy of Co-doped BaFe2As2 iron pnictide superconductors
K. Koepernik, S. Johnston, E. van Heumen +5
We establish in a combination of ab initio theory and experiments that the tunneling process in scanning tunneling microscopy/spectroscopy on the A-122 iron pnictide superconductor…
Bilayer manganites: polarons in the midst of a metallic breakdown
F. Massee, S. de Jong. Y. Huang, W. K. Siu +10
The exact nature of the low temperature electronic phase of the manganite materials family, and hence the origin of their colossal magnetoresistant (CMR) effect, is still under hea…
Pseudogap-less high T superconductivity in BaCoFeAs
F. Massee, Y. K. Huang, J. Kaas +6
The pseudogap state is one of the peculiarities of the cuprate high temperature superconductors. Here we investigate its presence in BaCoFeAs, a member of the p…
Existence, character and origin of surface-related bands in the high temperature iron pnictide superconductor BaFe_{2-x}Co_{x}As_{2}
Erik van Heumen, Johannes Vuorinen, Klaus Koepernik +8
Low energy electron diffraction (LEED) experiments, LEED simulations and finite slab density functional calculations are combined to study the cleavage surface of Co doped BaFe_{2-…
Droplet-like Fermi surfaces in the anti-ferromagnetic phase of EuFeAs, an Fe-pnictide superconductor parent compound
S. de Jong, E. van Heumen, S. Thirupathaiah +15
Using angle resolved photoemission it is shown that the low lying electronic states of the iron pnictide parent compound EuFeAs are strongly modified in the magnetically or…
