Magnetoelastic hybrid excitations in CeAuAl
Petr Čermák, Astrid Schneidewind, Benqiong Liu +5
The interactions between elementary excitations such as phonons, plasmons, magnons, or particle-hole pairs, drive emergent functionalities and electronic instabilities such as mult…
Antiferromagnetic correlations in the metallic strongly correlated transition metal oxide LaNiO
H. Guo, Z. W. Li, L. Zhao +10
The material class of rare earth nickelates with high Ni oxidation state is generating continued interest due to the occurrence of a metal-insulator transition with charge o…

We observe quasi-static incommensurate magnetic peaks in neutron scattering experiments on layered cobalt oxides La2-xSrxCoO4 with high Co oxidation states that have been reported…
Electronic and magnetic nano phase separation in cobaltates LaSrCoO
Z. W. Li, Y. Drees, A. Ricci +11
The single-layer perovskite cobaltates have attracted enormous attention due to the recent observation of hour-glass shaped magnetic excitation spectra which resemble the ones of t…
Soft striped magnetic fluctuations competing with superconductivity in Fe_{1+x}Te
C. Stock, E. E. Rodriguez, O. Sobolev +5
Neutron spectroscopy is used to investigate the magnetic fluctuations in Fe_{1+x}Te - a parent compound of chalcogenide superconductors. Incommensurate "stripe-like" excitations so…

E. E. Rodriguez, D. A. Sokolov, C. Stock +5
We construct a phase diagram of the parent compound Fe1+xTe as a function of interstitial iron x in terms of the electronic, structural, and magnetic properties. For a concentratio…
Distinguishing and electron pairing symmetries by neutron spin resonance in superconducting NaFeCoAs
Chenglin Zhang, H. -F. Li, Yu Song +17
A determination of the superconducting (SC) electron pairing symmetry forms the basis for establishing a microscopic mechansim for superconductivity. For iron pnictide superconduct…
Conformity of spin fluctuations in alkali-metal iron selenide superconductors inferred from the observation of a magnetic resonant mode in K(x)Fe(2-y)Se(2)
