Abstract Intraparticle entanglement of individual particles such as neutrons could enable another class of scattering probes that are sensitive to entanglement in quantum systems and materials.

In the iron–chromium system, FexCr1−x, a wide dome of spin-glass behavior emerges when the ferromagnetism of iron is suppressed and the antiferromagnetism of chromium emerges as a function of increasing iron content x. As both, the high-temperature state and the characteristic cluster size vary as a function of x, different regimes of spin-glass behavior may be compared in a single, isostructural material system.

Small-angle neutron scattering (SANS) is a widely used technique to study bulk samples with length scales in the range of 10–1000 nm. The isotope specificity of neutrons and their ability to interact with magnetic spins make SANS a powerful tool to determine the size and shape of structures in fields ranging from biology (Jeffries et al., 2021) to magnetism and superconductivity (Mühlbauer et al., 2019).

2.2. Transformation to reciprocal space To interpret 2D scattering images, the momentum transfer corresponding to each detector pixel needs to be calculated. The real-space angles of each pixel (in the LRF) provide the geometric basis for calculating the momentum transfer in reciprocal space (in the SRF). First, the out-of-scattering-plane angle ϕ is calculated pixelwise, with the scattering plane being the xz plane, by with the real-space coordinates (x, y, z).

The sample preparation is described by Eich et al. (2021). Neutron single-crystal diffraction at low temperatures and high pressures was performed using a TiZr clamp cell (03PCL150TZ5) on the beamline D9 at the Institut Laue–Langevin (ILL, Grenoble, France). The sample was an as-grown CrAs single crystal that was cut to the length of 3 mm along its growth a axis and had a final size of 3 × 2 × 2 mm.
