To continue to spread the interest in polarized-neutron diffraction amongst the physics, chemistry, material science and biology scientific communities, a three-day International Workshop on Single-Crystal Diffraction with Polarized Neutrons will be held at the ILL in Grenoble on 11th-13th December 2024. The workshop will focus on the application of half-polarized and polarization-analysis neutron methods to fundamental research and to functional research in areas with a strong societal impact, probing length scales from the atomic to mesoscopic in crystalline solids with a focus on multiferroic, topological, superconducting and other smart materials. The workshop aims to complement the broader scope offered by the biennial PNCMI, and will be run as a satellite to the ILL/ESS User Meeting, also in Grenoble.
