Dichotomous Electrons: Travelling without Moving
Neutron scattering experiments give new understanding of how localized and free-flowing electrons collaborate to create material functionality.
Field-tuned quantum renormalization of spin dynamics in the honeycomb lattice Heisenberg antiferromagnet YbCl3
The basis for our understanding of quantum magnetism has been the study of elegantly simple model systems. However, even for the antiferromagnetic honeycomb lattice with isotropic spin interactions – one of the simplest model systems – a detailed understanding of quantum effects is still lacking. Here, using inelastic neutron scattering measurements of the honeycomb lattice material YbCl3, we elucidate how quantum effects renormalize ...
Resonant Elastic X-Ray Scattering of Antiferromagnetic Superstructures in EuPtSi3
We report resonant elastic x-ray scattering of long-range magnetic order in EuPtSi3, combining different scattering geometries with full linear polarization analysis to unambiguously identify magnetic scattering contributions. At low temperatures, EuPtSi3 stabilizes type A antiferromagnetism featuring various long- wavelength modulations. For magnetic fields applied in the hard magnetic basal plane, well-defined regimes of cycloidal, conical, and fanlike superstructures may be distinguished that encompass a pocket of commensurate type A order without superstructure.

Swiss precision optics in Sweden
PSI has finalized the precision Selene neutron optics for the ESTIA instrument. The complex state-of-the-art guide was installed at the European Spallation Source as a Swiss in-kind delivery.
The Laboratory for Neutron and Muon Instruments visits FRM II neutron research facility
Recently, the staff of the PSI’s Laboratory for Neutron and Muon Instrumentation (LIN) visited our colleagues at MLZ to learn more about the FRM II reactor and its instrumentation, as well as to discuss current and future joint projects. LIN staff was greeted with Bavarian hospitality in the form of “Weisswurst Frühstück” and then enjoyed a full tour of the facility and many fruitful discussions.
Kinderuniversität Zürich visits PSI
On November 5, 2022, the Laboratory for Neutron and Muon Instrumentation in collaboration with the Correlated Quantum Matter group at the University of Zurich carried out the workshop “Wellenspiele” (German for “Playing with Waves”) for the Kinderuniversität Zürich (“Children’s University Zurich”) for the first time.
