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…
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…
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…
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…
