Record high-field superconductivity in MgB2: new perspectives for magnet technology

The quest for energy-efficient high-field magnets passes through the progress made on practical superconductors. Scientists from the Department of Quantum Matter Physics (UNIGE), the Laboratory of Advanced Technology – LTA (UNIGE, HES-SO Genève), and the Laboratoire des Champs Magnétiques Intenses of Grenoble (F) have recently shed light on the mechanisms that enhance the upper critical…

Talk with Mitali Banerjee, Professor, EPFL

What has been your primary field of research and your most surprising scientific finding during these last years ? I am an experimental physicist working in the world of two-dimension of solid state, namely, conductors, semiconductors, and insulators, at ultra-low temperature close to the absolute zero, and under the influence of very high magnetic fields…

Fractional antiferromagnetic skyrmion lattice induced by anisotropic couplings

Fractional antiferromagnetic skyrmion lattice induced by anisotropic couplings

By Oksana Zaharko, Paul Scherrer Institute Based on article published in Nature Magnetic skyrmions, swirling configurations with topological properties, typically exhibit nearly parallel alignment for neighbouring spins. Such particles with antiparallel near spins can be more easily controlled and are interesting for spintronic applications. By combining neutron scattering experiments with extensive Monto Carlo simulations we identify…

9th MaNEP Winter School postponed

9th MaNEP Winter School postponed

The recent surge of COVID-19 propagation in Switzerland and Europe makes it impossible to maintain the Saas-Fee school as originally planned in January 2021. After considering different options, the organizers, program committee, and MaNEP board members have decided to postpone the school by one year, tentatively keeping the scientific program unchanged. The option of an…

Making disorder for an ideal battery

Making disorder for an ideal battery

Manufacturing safer, more powerful batteries that use geopolitically stable resources requires solid electrolytes and replacing lithium with sodium. A chemical solution is now being offered to battery developers. The lithium batteries that power our electronic devices and electric vehicles have a number of drawbacks. The electrolyte – the medium that enables electrons and positive charges to…

Superconductivity with a twist explained

Superconductivity with a twist explained

Physicists have revealed what makes magic angle graphene so special. This is a key step elucidating the mystery behind superconductivity in this recently discovered material with potential for technological breakthroughs. Magic-angle materials represent a surprising recent physics discovery in double layers of graphene, the two-dimensional material made of carbon atoms in a hexagonal pattern. When…

Artificial materials for more efficient electronics

Artificial materials for more efficient electronics

The discovery of an unprecedented physical effect in a new artificial material marks a significant milestone in the lengthy process of developing “made-to-order” materials and more energy-efficient electronics. We are surrounded by electronic devices. Transistors are used to power telephones, computers, televisions, hi-fi systems and game consoles as well as cars, airplanes and the like.…

A breach in the “standard model” of quantum matter

A breach in the “standard model” of quantum matter

Professor Dirk van der Marel’s team from the Department of Quantum Matter Physics (DQMP) of Geneva University recently discovered a whole new effect in a magnetic material with a chemical composition of Nd2Ir2O7. At absolute zero (-273.15 degrees Celsius), this material is insulating but by increasing its temperature it becomes an electrical conductor. More precisely,…
