This contribution presents an overview of how neutrons support the development of gas turbinematerials and batteries due to their unique properties of being non-destructive, having a large beam cross section,offering relatively high sensitivity to light elements in the neighborhood of heavy elements and provingsuitable for in situ and/or operando studies. Various neutron techniques, together with sophisticated sampleenvironments, are applied to measure materials under real working conditions. [...]

We report a neutron-scattering study on Pr2−xSrxNiO4 (x≈0.5) with magnetic incommensurability ε=0.461 at 10 K, showing direct evidence for out-of-plane magnetic excitations caused by a non-negligible interlayer spin coupling (J⊥). The magnetic spectrum is fully represented by linear spin wave theory considering an unconventional body-centered-like stacking of discommensurated spin stripes. [...]

The effect of structural properties on the formation of the perpendicular magnetic anisotropy in Co/Dy superlattices has been studied. The superlattices are found to be composition-modulated alloys in which, on the one hand, a rigid periodicity in thicknesses and compositions takes place and, on the other hand, the interdiffusion of Co and Dy at interlayer boundaries leads to a periodic change in the Co and Dy concentrations with depth.

Rapid cooling rates and steep temperature gradients are characteristic of additivelymanufactured parts and important factors for the residual stress formation. This study examined theinfluence of heat accumulation on the distribution of residual stress in two prisms produced by LaserPowder Bed Fusion (LPBF) of austenitic stainless steel 316L. [...]
