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…
Magnetic Frustration in CuYbSe: an Yb-Based Triangular Lattice Selenide
Barkha Khattar, Anzar Ali, Masahiko Isobe +1
The Yb based triangular lattice delafossites Yb ( = alkali metal, = O, S, Se) have recently been studied as quantum spin liquid candidates. We report the synthesis o…
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…
