  • EuIn2As2 is a candidate as an axion insulator, a material that can host axion-like quasi-particles, in direct analogy with the axion proposed in particle physics to resolve the so called “strong CP problem”. Here Soh et al., perform resonant elastic X-Ray scattering on EuIn2As2 and show that the magnetic order consists of commensurate chiral magnetic structures, satisfying the symmetry requirements for EuIn2As2 to be an axion insulator.’

  • Multiferroic materials can host intriguing phenomena due to the simultaneous breaking of both spatial inversion symmetry and time reversal symmetry. Here, three-dimensional imaging of topologically protected strings in a single hexagonal manganite nanocrystal is reported, providing a crystallographic testing ground for exploring cosmological concepts.

  • The authors present a 3D determination of the ferroelectric domain structure in a hexagonal yttrium manganite nanocrystal using multi-peak Bragg coherent x-ray diffraction imaging and reconstructing the full displacement field and strain tensor

  • In magnetoelectric materials, the magnetization can be controlled by the application of an electric field, making it comparatively easy to switch magnetization, which is attractive for data storage and other proposed devices. Unfortunately, the effect in single-phase materials is typically fairly weak. Here Fogh et al. demonstrate a two orders of magnitude enhancement of the magnetoelectric coupling in LiNi0.8Fe0.2PO4 compared to the parent compounds.

  • The reversal of spin chirality in the absence of any externally applied field would substantially broaden the use of chiral magnets for applications in spintronic devices. In this manuscript the authors demonstrate the spontaneous reversal of spin chirality in the topological magnet EuAl4 using resonant elastic x-ray scattering.

  • Although lithium cobalt(III) oxide (LCO) is a widely used and highly stable lithium-ion battery material, several challenges still need to be overcome. Here, the authors use in-operando Bragg Coherent X-ray Diffraction Imaging to visualize the structural properties of LCO in battery cells and identify inefficiency-increasing domain dynamics during cycling.
