Observation of the spiral spin liquid in a triangular-lattice material

Nature Communications
The spiral spin liquid (SSL) is a highly degenerate state characterized by a continuous contour or surface in reciprocal space spanned by a spiral propagation vector.

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 ...

Spatial Engineering of Gas Diffusion Layers Overcomes Mass Transport Limitations in Fuel Cells

Advanced Science, EarlyView.
ABSTRACT Mass transport limitations at high current densities hinder polymer electrolyte fuel cell (PEFC) performance due to inefficient water management and reactant distribution. Gas diffusion layer (GDL) perforation offers a potential solution as an alternative to complex flow‐field modifications.

Neutron Bragg edge imaging for strain and texture characterization of steel-copper multi-material obtained by laser powder-bed fusion

Materials & Design
Bragg edge imaging has been applied to multi-material laser powder-bed fusion (M2LPBF) samples of 316 L stainless steel and CuCrZr. A multilayer sample with interfaces perpendicular to the building direction and a bilayer sample with a parallel interface

Engineering of Crystal and Domain Structures in Epitaxial Y:HfO2 Thin Films by YSZ Substrate Miscut

Advanced Science, EarlyView.
We investigate how YSZ substrate miscut influences crystal structure and domain formation in epitaxial Y‐doped HfO2 thin films. Using magnetron sputtering, high‐resolution X‐ray diffraction, atomic‐resolution scanning transmission electron microscopy, and first‐principles calculations, we systematically examine the characteristics of thickness‐ and ...

Flat-band hybridization between f and d states near the Fermi energy of SmCoIn5

npj Quantum Materials
We 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 ...

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 ...

Harnessing Phase Separation for the Development of High‐Performance Hydrogels

Advanced Science, EarlyView.
ABSTRACT Hydrogels are indispensable for the development of next‐generation bioelectronics, soft robotics, and biomedical devices, where their mechanical properties determine performance and reliability. Among strategies to enhance hydrogel mechanics, phase separation enables controlled heterogeneity resulting in gel networks that are reinforced by ...

Deterministic control of nanomagnetic spiral trajectories using an electric field

Nature Communications
The intertwined nature of magnetic and electric degrees of freedom in magnetoelectric (ME) materials is well described by ME-coupling theory. When an external electric field is applied to a ME material, the ME coupling induces unique and intriguing ...
