Transition énergétique

Abandon de l’énergie nucléaire, développement de l’énergie solaire et éolienne, production d’énergie à partir de la biomasse, réduction de la consommation d’énergie. D’ici 2050, la Suisse doit atteindre la neutralité climatique. Un objectif ambitieux, rendu plus urgent que jamais par une situation géopolitique de plus en plus difficile. Comment faire pour mettre en place ces prochaines années un approvisionnement énergétique durable et résistant pour la Suisse? Comment les énergies renouvelables peuvent-elles être utilisées de manière optimale? Quelles sont les nouvelles technologies les plus prometteuses? Au PSI, des chercheurs s’efforcent de trouver des réponses à ces questions décisives.

Discovery of Charge Order and Corresponding Edge State in Kagome Magnet FeGe

Kagome materials often host exotic quantum phases, including spin liquids, Chern gap, charge density wave, and superconductivity. Existing scanning microscopy studies of the kagome charge order have been limited to nonkagome surface layers. Here, we tunnel into the kagome lattice of FeGe to uncover features of the charge order. Our spectroscopic imaging identifies a 2 × 2 charge order in the magnetic kagome lattice, resembling that discovered in kagome superconductors. Spin mapping across steps of unit cell height demonstrates the existence of spin-polarized electrons with an antiferromagnetic stacking order.

30th Conference of the International Nuclear Target Development Society

The Isotope and Target Chemistry group of the Paul Scherrer Institut had the pleasure to organize and host the 30th Conference of the International Nuclear Target Development Society (INTDS 2022) at PSI from 25th to 30th September 2022.

The conference was a great success! 80 participants, representing scientific institutions of 14 different countries and 4 continents, met in person, discussed and presented their newest results on target preparation methods, advances in target characterization, production of targets for medical applications, gas targets, stripper films, high-power target technology and much more. We are happy to emphasise the relative large number of students, 15, participating to the event.

Special thanks to the Local Organizing Committee: D. Schumann (Chair), Z. Talip, E.A. Maugeri, R. Dressler, K. Daniela, A. Blattmann, M. Veicht, N. Cerboni

Ready for SLS2.0: First magnet series measurement completed

The first magnet series consisting of 112 quadrupole electromagnets for SLS2.0 were measured to high precision using a special home-made rotating coils measurement system. This is an important step forward for the realization of SLS2.0, the upgrade of the Swiss Light Source (SLS) at PSI, and a milestone for the members of the Magnet Section in GFA.

feM-LEAD am PSI, der Empa und der WSL fka. Mentoring-Programm für Frauen mit Führungsambitionen

Das Mentoring-Programm ist ein kompetitives Programm, das sich an Frauen richtet, die in Zukunft eine Führungsrolle übernehmen möchten. Es startete erstmalig 2018 am PSI und beendete seine Pilotphase Ende 2020. Das Mentoring-Programm wird über diese Phase hinaus fortgeführt und wurde extern als einzigartig evaluiert, da es:

- offen für alle Frauen ist (d.h. Wissenschaftlerinnen (nach Postdoc), Technikerinnen sowie Frauen, die in der Administration tätig sind)

- offen für Frauen ist, die noch keine Führungsrolle übernommen haben

Erstmalig steht das Programm auch offen für ambitionierte Mentees und Mentor*innen aus der Empa und der WSL.

Folge diesem Link für mehr Informationen zur Ausschreibung.

SAF Skyrmion Nucleation

Nucleation of synthetic antiferromagnetic skyrmions

Magnetic skyrmions stabilized in synthetic antiferromagnets hold promise as nanoscale information carriers in novel non-volatile magnetic memory designs. In this work, scientists in a worldwide collaborative effort have demonstrated the electrically-induced nucleation of magnetic skyrmions in synthetic antiferromagnets, which is a vital stepping stone towards the applicability of these magnetic textures in devices.

Ferrimagnetic Skyrmions: fast and straight

Scientists have demonstrated, through magnetic X-ray microscopy, that magnetic skyrmions stabilized in ferrimagnetic heterostructures can be displaced by electrical currents at high velocities, and exhibit low deflection angles, proving that ferrimagnetic skyrmions are good candidates for fast skyrmionic devices.

Two types of charge order with distinct interplay with superconductivity in the kagome material CsV3Sb5

The kagome metals of the family AV3Sb5, featuring a unique structural motif, harbor an array of intriguing phenomena such as chiral charge order and superconductivity. CsV3Sb5 is of particular interest because it displays a double superconducting dome in the region of the temperature-pressure phase diagram where charge order is still present. However, the microscopic origin of such an unusual behavior remains an unsolved issue. Here, to address it, we combine high-pressure, low-temperature muon spin relaxation/rotation with first-principles calculations. We observe ....
