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 La2PrNi2O7 and La3Ni2O7. While La2PrNi2O7 exhibits bulk superconductivity, La3Ni2O7 displays filamentary behavior, suggesting that superconductivity is confined to phase interfaces rather than the bulk. Since magnetism emerges ...
Pressure tuning of competing interactions on a honeycomb lattice
Exchange interactions are mediated via orbital overlaps across chemical bonds. Thus, modifying the bond angles by physical pressure or strain can tune the relative strength of competing interactions. Here we present a remarkable case of such tuning between the Heisenberg (J) and Kitaev (K) exchange, which respectively establish magnetically ordered and spin liquid phases on a honeycomb lattice. We observe ...
Tailoring the Normal and Superconducting State Properties of Ternary Scandium Tellurides, Sc6MTe2 (M = Fe, Ru, and Ir) Through Chemical Substitution
The pursuit of a unifying theory for non-BCS superconductivity has faced significant challenges. One approach to overcome such challenges is to perform systematic investigations into superconductors containing d-electron metals in order to elucidate their underlying mechanisms. Recently, the Sc6MTe2 (M = d-electron metal) family has emerged as a unique series of isostructural compounds exhibiting superconductivity across a range of 3d, 4d, and 5d electron systems.
In this study, muon spin rotation, neutron diffraction, and magnetization techniques are employed to probe ...

Developments of the MIXE technique at PSI
With muons, PSI researchers can examine objects non-destructively. This helps in archaeology and battery development.
