Statistical Uncertainty in Quantitative Neutron Radiography
, 2017 We demonstrate a novel procedure to calibrate neutron detection systems commonly used in standard neutron radiography. This calibration allows determining the uncertainties due to Poisson-like neutron counting statistics for each individual pixel of a ...

Electromagnon dispersion probed by inelastic X-ray scattering in LiCrO2
Nature Communications, 2016 Whilst terahertz optical spectroscopy allows for the study of coupled spin and lattice excitations, it is limited in momentum space. Here, the authors use inelastic x-ray scattering to demonstrate strong magnon-phonon coupling and electromagnon ...

Neutron optics requirements for neutron imaging techniques
Journal of Physics: Conference Series, 2014 The utilization of X-rays for material research is common in many respects since their discovery at the end of the 19th century. New sources as electron synchrotrons or free-electron lasers push the methodology and the application ranges further. A similar approach started 50 years later with neutrons when sources with reasonable high intensity became ...

Coupled multiferroic domain switching in the canted conical spin spiral system Mn2GeO4
Nature Communications, 2017 The coexistence of ferromagnetism and ferroelectricity in a multiferroic material often arises from complex magnetoelectric couplings. Here, the authors observe switching of domains in Mn2GeO4using neutron diffraction and develop a phenomenological ...

Flat-band hybridization between f and d states near the Fermi energy of SmCoIn5
npj Quantum MaterialsWe present high-quality angle-resolved photoemission (ARPES) and density functional theory calculations (DFT+U) of SmCoIn5. We find broad agreement with previously published studies of LaCoIn5 and CeCoIn5 1,2, confirming that the Sm 4f electrons are ...

Distinct domain switching in Nd0.05Ce0.95CoIn5 at low and high fields
Scientific Reports, 2018 Nd0.05Ce0.95CoIn5 features a magnetic field-driven quantum phase transition that separates two antiferromagnetic phases with an identical magnetic structure inside the superconducting condensate.
