A New Quantum Landscape: Coexisting High-Tc Superconductivity, Magnetism, and Complex Charge Order in LaRu3Si2.

Despite intense research on kagome superconductors, many fundamental questions remain—especially regarding the unconventional nature of their charge order and superconducting phases. These materials are rich in complexity, and to truly unravel their behavior, a broad and integrated approach is essential. In our study ...

Understanding and Addressing the Performance Asymmetry Issue in Semitransparent Laminated Organic Photovoltaic Devices

Organic photovoltaics (OPVs) offer a promising solution for indoor energy harvesting. However, fundamental investigations to understand and optimize industrial processes such as roll-to-roll lamination for upscaling remain limited. This study investigates a critical failure mode in the upscaling of OPVs. 

One major challenge ...

Absence of Altermagnetic Magnon Band Splitting in MnF2

Altermagnets are collinear compensated magnets in which the magnetic sublattices are related by rotation rather than translation or inversion. One of the quintessential properties of altermagnets is the presence of split chiral magnon modes. Recently, such modes have been predicted in MnF2

Here, we report inelastic neutron scattering results ...

Pressure effect on the spin density wave transition in La2PrNi2O6.96

High-pressure studies reveal a stark contrast between the superconducting properties of double-layer Ruddlesden-Popper (RP) nickelates La2⁢PrNi2⁢O7 and La3⁢Ni2⁢O7. While La2⁢PrNi2⁢O7 exhibits bulk superconductivity, La3⁢Ni2⁢O7 displays filamentary behavior, suggesting that superconductivity is confined to phase interfaces rather than the bulk. Since magnetism emerges ...

300

The CNM center hosts 300 members of staff, in addition 40 PhD students perform their thesis work within CNM

5+1

The center is organized in 5 laboratories and 1 staff group.

3/30

CNM operates 3 of the 5 large scale user facilities: the Swiss spallation neutron source SINQ, the Swiss Muon Source SμS and the facilities for particle physics CHIRSP with approximately 30 experimental stations open for users.

1700

The facilities in the CNM center are open to international access — with approximately 1700 annual user visits the associated user program is a key activity for the center and for PSI as a whole.
