Topochemical Fluorination of LaNiO Single Crystals
Hasan Yilmaz, Masahiko Isobe, Oliver Clemens +1
Topochemical fluorination offers a low--temperature route for modifying the anion chemistry and electronic ground states of layered transition-metal oxides, providing access to met…
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…
Terahertz light driven coherent excitation of a zone-folded Raman-active phonon mode in the Spin-Ladder System -NaVO
Flavio Giorgianni, Martina Romani, Pascal Puphal +5
We investigate the out-of-equilibrium lattice dynamics in the spin-ladder system -NaVO using intense terahertz (THz) pump and near-infrared (NIR) probe spectroscopy. Wh…
Spinon mediation of witness spin dynamics in herbertsmithite
Hiroto Takahashi, Jack Murphy, Mitikorn Wood-Thanan +12
The kagome lattice of spin-1/2 copper atoms in herbertsmithite is conjectured to sustain a quantum spin liquid state with spinon quasiparticles. Ideally, the kagome crystal planes…
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…
Exploring Low-Dimensional Magnetism in Cobalt Vanadates, CoVO~(~=~Ca, Sr) : Crystal Growth and Magnetic Properties of Effective Spin-1/2 Zigzag Chains
Anzar Ali, Guratinder Kaur, Arvind Maurya +6
We report the successful growth of high-quality single crystals of \ACVO, a quasi-one-dimensional zigzag chain compound containing Co ions, using the optical floating zone m…
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…
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…
Realization of a classical Ruddlesden Popper type bilayer nickelate in SrNiAlO with unusual Ni
Hasan Yilmaz, Kathrin Küster, Ulrich Starke +3
The discovery of 80 K superconductivity in bilayer LaNiO at pressures greater than 14 GPa presents a unique opportunity to study a novel class of high-temperature super…
