The discovery of superconductivity at in the infinite-layer nickelate , followed by superconductivity at …
Unveiling orbital landscapes in strongly correlated bulk nickelates with -NIXS
Edgar Abarca Morales, Martin Sundermann, Brett Leedahl +10
We leverage -orbital non-resonant inelastic X-ray scattering (-NIXS) to perform orbital imaging on three bulk rare-earth nickelates spanning a range of formal nickel valence…
Imaging stripe dynamics in trilayer nickelate LaNiO
Uladzislau Mikhailau, Luke Rhodes, Siri A. Berge +5
Since the discovery of high-temperature superconductivity in nickelate superconductors, it is an open question how closely the superconducting state resembles that of cuprate super…
Anisotropic magnetoelastic coupling in the honeycomb magnet NaCoSbO
Prashanta K. Mukharjee, Sebastian Erdmann, Lichen Wang +8
We present magnetization and dilatometry measurements on the honeycomb cobaltate NaCoSbO and map out its detailed field-temperature phase diagram down to sub-Kelvin tem…
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…
Comparative Raman study of Ruddlesden-Popper nickelates and the monolayer-trilayer polymorph
Vignesh Sundaramurthy, Abhi Suthar, Pascal Puphal +12
Ruddlesden-Popper (RP) nickelates have attracted intense interest following the discovery of superconductivity in several members of the series, including bilayer (BL) LaNi…
Lattice dynamics of the infinite-layer nickelate LaNiO
Shohei Hayashida, Vignesh Sundaramurthy, Wenfeng Wu +8
Infinite-layer (IL) nickelates have rapidly emerged as a new class of superconductors. However, due to the technical challenges of their topotactic synthesis, they have so far been…
Multiorbital character of the density wave in trilayer nickelate superconductors
A. Suthar, V. Sundaramurthy, M. Bejas +15
Ruddlesden-Popper nickelates exhibit high-temperature superconductivity closely intertwined with charge and spin density waves. However, fundamental questions persist regarding the…
Direct Evidence of Metal-Ligand Redox in Li-ion Battery Positive Electrodes
Galo J. Paez Fajardo, Daniela Dogaru, Hrishit Banerjee +15
Describing Li-ion battery positive electrodes in terms of distinct transition metal or oxygen redox regimes can lead to confusion in understanding metal-ligand hybridisation, oxyge…
Non-volatile multi-state electrothermal resistive switching in a strongly correlated insulator thin-film device
Farnaz Tahouni-Bonab, Matthias Hepting, Theodor Luibrand +7
Strongly correlated insulators, such as Mott or charge-transfer insulators, exhibit a strong temperature dependence in their resistivity. Consequently, self-heating effects can lea…
Unraveling nano-scale effects of topotactic reduction in LaNiO crystals
Yu-Mi Wu, Pascal Puphal, Masahiko Isobe +4
Infinite-layer nickelates stand as a promising frontier in the exploration of unconventional superconductivity. Their synthesis through topotactic oxygen reduction from the parent…
Electronic structure of the alternating monolayer-trilayer phase of La3Ni2O7
Sebastien N. Abadi, Ke-Jun Xu, Eder G. Lomeli +12
Recent studies of LaNiO have identified a bilayer (2222) structure and an unexpected alternating monolayer-trilayer (1313) structure, both of which feature signatures o…
Synthesis and physical properties of LaNiO crystals
Pascal Puphal, Björn Wehinger, Jürgen Nuss +6
Infinite-layer (IL) nickelates are an emerging family of superconductors whose similarities and differences to cuprate superconductors are under intense debate. To date, the IL pha…
