La recherche énergétique de l’Institut Paul Scherrer se concentre sur la recherche de procédés susceptibles d’être utilisés dans des technologies durables et sûres pour un approvisionnement en énergie si possible exempt d’émissions CO2. Les énergies renouvelables constituent un point fort important. A la plateforme ESI (Energy System Integration), la recherche et l’industrie peuvent tester des solutions d’intégration d’énergies renouvelables. Un autre point fort de ce domaine est l’utilisation sûre de l’énergie nucléaire. Ces activités sont complétées par des analyses d’évaluation globale des systèmes énergétiques. Le PSI mène également de la recherche climatique et environnementale sur les processus chimiques qui se jouent dans l’atmosphère.

Pressure-enhanced splitting of density wave transitions in La3Ni2O7–δ
The observation of superconductivity in La3Ni2O7–δ under pressure, following the suppression of a high-temperature density wave state, has attracted considerable attention. The nature of this density wave order was not clearly identified. Here we probe the magnetic response of the zero-pressure phase of La3Ni2O7–δ as hydrostatic pressure is applied, and find that the apparent single density wave transition at zero applied pressure splits into two. The comparison of our muon-spin rotation ...

Spin-orbit control of antiferromagnetic domains without a Zeeman coupling
Encoding information in antiferromagnetic (AFM) domains is a promising solution for the ever growing demand in magnetic storage capacity. The absence of a macroscopic magnetization avoids crosstalk between different domain states, enabling ultrahigh density spintronics while being detrimental to the domain detection and manipulation. Disentangling these merits and disadvantages seemed so far unattainable. We report evidence ...

Electronic Commensuration of a Spin Moiré Superlattice in a Layered Magnetic Semimetal
Spin moiré superlattices (SMSs) formed by interfacing conventional electronic states with a multi-q magnetic lattice have been proposed as a magnetic analog of crystallographic moiré systems. The electron-minibands created in an SMS are expected to be enriched by the vector-field nature of the magnetic interaction and offer new types of moiré tunability, topological protection, and Berry curvature effects. However, most spin-vortex-hosting systems discovered to date have carrier mean free paths lmfp significantly shorter than their spin-moiré lattice constant aspin, inhibiting mini-band-formation. Furthermore ...
Evolution of texture and residual stresses in 2205 duplex stainless steel during laser powder bed fusion
This study uses a custom-designed laser powder bed fusion machine, capable of operating in neutron instruments, to track metallic material evolution during additive manufacturing process. More specifically, it investigates the development of residual stresses in textured 2205 duplex stainless steel during laser powder bed fusion. In situ and operando neutron diffraction experiments were conducted to study the transient and real-time evolution of stresses and strains during processing, using an AM machine designed for neutron studies. Additionally, Bragg-edge imaging was employed to investigate the crystallographic texture. The results showed that residual stress redistribution primarily occurs in the first set of added layers when further layers are added on top. The cube texture observed in the sample significantly affects residual stress determination, leading to inaccuracies up to 96 MPa if not accounted for. This highlights the need for orientation-dependent diffraction elastic constants in residual stress calculations. Furthermore, variations in texture intensity across the sample dimensions were found to be driven by changes in the local temperature history, which were deciphered from real-time strain measurements. Finally, this study demonstrates the potential of combining laser powder bed fusion with neutron diffraction to investigate the underlying mechanisms of additive manufacturing in the bulk of the sample.
Anisotropic Skyrmion and Multi-q Spin Dynamics in Centrosymmetric Gd2PdSi3
Skyrmions are particlelike vortices of magnetization with nontrivial topology, which are usually stabilized by Dzyaloshinskii-Moriya interactions (DMI) in noncentrosymmetric bulk materials. Exceptions are centrosymmetric Gd- and Eu-based skyrmion-lattice (SL) hosts with zero DMI, where both the SL stabilization mechanisms and magnetic ground states remain controversial. We address these here by investigating both the static and dynamical spin properties ...
