SwissFEL

Die jüngste Grossforschungsanlage des PSI erzeugt sehr kurze Pulse von Röntgenlicht mit Lasereigenschaften. Damit können Forschende extrem schnelle Vorgänge wie die Entstehung neuer Moleküle bei chemischen Reaktionen verfolgen, die detaillierte Struktur lebenswichtiger Proteine bestimmen oder den genauen Aufbau von Materialien klären. Die Erkenntnisse erweitern unser Verständnis der Natur und führen zu praktischen Anwendungen wie etwa neuen Medikamenten, effizienteren Prozessen in der chemischen Industrie oder neuen Materialien in der Elektronik.

Unconventional charge order and superconductivity in kagome-lattice systems as seen by muon-spin rotation

Kagome lattices are intriguing and rich platforms for studying the intertwining of topology, electron correlation, and magnetism. These materials have been subject to tremendous experimental and theoretical studies not only due to their exciting physical properties but also as systems that may solve critical technological problems. We will review recent experimental progress on superconductivity and magnetic fingerprints of charge order in several kagome-lattice systems from the local-magnetic probe point of view by utilizing muon-spin rotation under extreme conditions, i.e., hydrostatic pressure, ultra low temperature and high magnetic field.

Strong phonon softening and avoided crossing in aliovalence-doped heavy-band thermoelectrics

Aliovalent doping is a way to optimize the electrical properties of semiconductors, but its impact on the phonon structure and propagation is seldom considered properly. Here we show that aliovalent doping can be much more effective in reducing the lattice thermal conductivity of thermoelectric semiconductors than the commonly employed isoelectronic alloying strategy. We demonstrate ...

Direct observation of exchange anisotropy in the helimagnetic insulator Cu2OSeO3

The helical magnetic structures of cubic chiral systems are well explained by the competition among Heisen- berg exchange, Dzyaloshinskii-Moriya interaction, cubic anisotropy, and anisotropic exchange interaction (AEI). Recently, the role of the latter has been argued theoretically to be crucial for the low-temperature phase diagram of the cubic chiral magnet Cu2OSeO3, which features tilted conical and disordered skyrmion states for a specific orientation of the applied magnetic field (μ0H⃗ ∥ [001]). In this study ...

Emergent Magnetism with Continuous Control in the Ultrahigh-Conductivity Layered Oxide PdCoO2

The current challenge to realizing continuously tunable magnetism lies in our inability to systematically change properties, such as valence, spin, and orbital degrees of freedom, as well as crystallographic geometry. Here, we demonstrate that ferromagnetism can be externally turned on with the application of low-energy helium implantation and can be subsequently erased and returned to the pristine state via annealing.
