Barely larger than a fingernail, the miniature Roman box lock from the 3rd or 4th century AD
Barely larger than a fingernail, the miniature Roman box lock from the 3rd or 4th century AD is skilfully crafted out of gold. The iron mechanism inside remained hidden for a long time because conventional imaging techniques were thwarted by the dense gold casing. It was only with the help of neutron tomography at PSI that the box lock could finally be deciphered non-destructively. © LWL/S. Brentführer

Understanding and Addressing the Performance Asymmetry Issue in Semitransparent Laminated Organic Photovoltaic Devices

Organic photovoltaics (OPVs) offer a promising solution for indoor energy harvesting. However, fundamental investigations to understand and optimize industrial processes such as roll-to-roll lamination for upscaling remain limited. This study investigates a critical failure mode in the upscaling of OPVs. 

One major challenge ...

Absence of Altermagnetic Magnon Band Splitting in MnF2

Altermagnets are collinear compensated magnets in which the magnetic sublattices are related by rotation rather than translation or inversion. One of the quintessential properties of altermagnets is the presence of split chiral magnon modes. Recently, such modes have been predicted in MnF2. 

Here, we report inelastic neutron scattering results ...

Pressure effect on the spin density wave transition in La2PrNi2O6.96

High-pressure studies reveal a stark contrast between the superconducting properties of double-layer Ruddlesden-Popper (RP) nickelates La2⁢PrNi2⁢O7 and La3⁢Ni2⁢O7. While La2⁢PrNi2⁢O7 exhibits bulk superconductivity, La3⁢Ni2⁢O7 displays filamentary behavior, suggesting that superconductivity is confined to phase interfaces rather than the bulk. Since magnetism emerges ...

Pressure tuning of competing interactions on a honeycomb lattice

Exchange interactions are mediated via orbital overlaps across chemical bonds. Thus, modifying the bond angles by physical pressure or strain can tune the relative strength of competing interactions. Here we present a remarkable case of such tuning between the Heisenberg (J) and Kitaev (K) exchange, which respectively establish magnetically ordered and spin liquid phases on a honeycomb lattice. We observe ...

Swiss Spallation Neutron Source SINQ

Neutron scattering techniques are highly versatile and powerful tools for studying the structure and dynamics of condensed matter. A wide scope of problems, ranging from fundamental to solid state physics and chemistry, and from materials science to biology, medicine and environmental science, can be investigated with neutrons. In addition to scattering, non-diffractive methods like imaging techniques allows for non-destructive inspection of materials and components, providing information on their internal structure, composition, and integrity with growing relevance also for industrial applications.
