Three PSI research facilities reveal magnetic crossover
Insights from the Swiss Muon Source, Swiss Spallation Neutron Source and Swiss Light Source reveal this coveted characteristic in an exotic layered material.
Neutron scattering collaboration with Norwegian Institute for Energy Technology
A collaboration between the Institute for Energy Technology (IFE) and the Paul Scherrer Institut (PSI) provides dedicated beam-time to Norwegian scientists, bringing with them diverse and exciting topics ranging from revealing hidden inscriptions in amulets to neutron based cancer therapies.
Spin Density Wave versus Fractional Magnetization Plateau in a Triangular Antiferromagnet
We report an excellent realization of the highly nonclassical incommensurate spin-density wave (SDW) state in the quantum frustrated antiferromagnetic insulator Cs2CoBr4. In contrast to the well-known Ising spin chain case, here the SDW is stabilized by virtue of competing planar in-chain anisotropies and frustrated interchain exchange.
Dynamic magnetic crossover at the origin of the hidden-order in van der Waals antiferromagnet CrSBr
The van-der-Waals material CrSBr stands out as a promising two-dimensional magnet. Here, we report on its detailed magnetic and structural character- istics. We evidence that it undergoes a transition to an A-type anti- ferromagnetic state below TN ≈ 140 K with a pronounced two-dimensional character, preceded by ferromagnetic correlations within the monolayers. Furthermore, we unravel the low-temperature hidden-order within the long- range magnetically-ordered state. We find that it is associated to a slowing down of the magnetic fluctuations, accompanied by a continuous reorienta- tion of the internal field.
