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 ...

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 ...

The anomalous Hall effect (AHE) has emerged as a key indicator of time-reversal symmetry breaking (TRSB) and topological features in electronic band structures. Absent of a magnetic field, the AHE requires spontaneous TRSB but has proven hard to probe due to averaging over domains. The anomalous component of the Hall effect is thus frequently derived from extrapolating the magnetic field dependence of the Hall response. We show ....
