Evolution of plasmon excitations across the phase diagram of the cuprate superconductor LaSrCuO
M. Hepting, T. D. Boyko, V. Zimmermann +19
We use resonant inelastic x-ray scattering (RIXS) at the O - and Cu -edges to investigate the doping- and temperature dependence of low-energy plasmon excitations in La$_{2-x…
Strain and electric field control of magnetic and electrical transport properties in a magneto-elastically coupled Fe3O4/BaTiO3(001) heterostructure
Gyanendra Panchal, Danny Kojda, Sophia Sahoo +9
We present a study of the control of electric field induced strain on the magnetic and electrical transport properties in a magneto-elastically coupled artificial multiferroic Fe3O…
Critical magnetic fluctuations in the layered ruthenates CaRuO and CaRuO
H. Trepka, T. Keller, M. Krautloher +5
Materials realizing the XY model in two dimensions (2D) are sparse. Here we use neutron triple-axis spectroscopy to investigate the critical static and dynamical magnetic fluctuati…
Water adsorption enhances electrical conductivity in transparent p-type CuI
Andrea Crovetto, Hannes Hempel, Marin Rusu +4
CuI has been recently rediscovered as a p-type transparent conductor with a high figure of merit. Even though many metal iodides are hygroscopic, the effect of moisture on the elec…
Characterization of the soft X-ray spectrometer PEAXIS at BESSY II
Christian Schulz, Klaus Lieutenant, Jie Xiao +3
The performance of the recently commissioned spectrometer PEAXIS for resonant inelastic soft X-ray scattering (RIXS) and X-ray photoelectron spectroscopy (XPS) and its hosting beam…
Time-dependent correlations in quantum magnets at finite temperature
B. Fauseweh, F. Groitl, T. Keller +4
In this article we investigate the time dependence of the gap mode of copper nitrate at various temperatures. We combine state-of-the-art theoretical calculations with high precisi…
