Unconventional superconductivity in ScIr chiral crystal with a kagome lattice
Keqi Xia, Jianzhou Zhao, Igor Plokhikh +6
Materials with a kagome lattice host exotic quantum phenomena driven by the interplay between band topology, spin-orbit coupling, magnetism, and electronic correlations. While magn…
Pressure-Invariant Isotope Effect as Evidence for Electronically Driven Intertwined Order in PrNiO
Rustem Khasanov, Thomas J. Hicken, Igor Plokhikh +5
We report muon-spin rotation measurements of the pressure dependence of the oxygen-isotope (O/O) effect on the spin-density wave (SDW) transition in the trilayer Rudd…
Multiple Magnetic Transitions in the Trilayer Nickelate PrNiO Revealed by Muon-Spin Rotation
Rustem Khasanov, Thomas J. Hicken, Zurab Guguchia +7
A muon-spin rotation/relaxation (SR) study of the trilayer Ruddlesden--Popper nickelate PrNiO was performed at ambient pressure and under hydrostatic pressure up…
Oxygen-isotope effect on density wave transitions in LaNiO
Rustem Khasanov, Vahid Sazgari, Igor Plokhikh +11
TThe isotope effect is a powerful probe of electron-phonon interactions in solid-state systems, offering key insights into how atomic mass influences emergent quantum states. Here,…
Magnetism of the alternating monolayer-trilayer phase of LaNiO
Rustem Khasanov, Thomas J. Hicken, Hubertus Luetkens +9
Understanding the magnetic ground state of Ruddlesden-Popper nickelates is crucial, as these materials exhibit superconductivity under high pressure and host competing electronic o…
Pressure Effect on the Spin Density Wave Transition in LaPrNiO
Rustem Khasanov, Igor Plokhikh, Thomas J. Hicken +3
High-pressure studies reveal a stark contrast between the superconducting properties of double-layer Ruddlesden-Popper (RP) nickelates LaPrNiO and LaNiO. Wh…
