Competing interactions in quantum spin systems with geometric frustration can lead to disordered but highly correlated spin states. For decades, experimental research on antiferromagnetic (AFM) quantum kagome materials has been driven primarily by the hunt for the quantum spin liquid (QSL) ground state. [...]

POLI is a hot neutron two-axis diffractometer at the Heinz Maier-Leibnitz Zentrum (MLZ), Germany, which uses spin-polarized neutrons for magnetic studies in particular. The instrument is used, for instance, to study complex magnetic structures, to reconstruct magnetization densities in the unit cell, and to explore phase diagrams of materials via multiparameter studies. [...]

The layered honeycomb magnet α-RuCl3 has attracted intense scrutiny as a prime candidate for realizing the Kitaev quantum spin liquid, yet a consensus on its spin Hamiltonian remains elusive due to the material’s extreme sensitivity to subtle structural details. Here, we report a comprehensive re-examination of the low-temperature crystallographic and magnetic structures of high-quality α-RuCl3 single crystals using unpolarized and polarized neutron diffraction [1] [...]

Resonant neutron reflectometry is a powerful probe of hydrogen absorption in thin layers, offering high depthsensitivity and low measurement time. In the case of a hydrogen barrier layer which hinders diffusion theconcentration gradient modifies the resonance conditions in the reflectometric measurement [...]

A topical exchange entitled “Future Trends in Neutron Science – User Needs and Community Collaboration” was jointly organized by the Asia-Oceania Neutron Scattering Association (AONSA), the Neutron Scattering Society of America (NSSA), and the European Neutron Scattering Association (ENSA) during the International Conference on Neutron Scattering (ICNS) 2025 [Citation1]. The conference took place from 6 to 10 July 2025 in Copenhagen (Denmark) and Lund (Sweden), and the session was held on Wednesday, 9 July 2025, as one of the parallel afternoon sessions.The objective of the exchange was to (i) identify new scientific trends in neutron science and the experimental needs that will arise from them and (ii) translate community perspectives into actionable recommendations for user groups, neutron facilities, funding bodies, and policymakers.
