Imaging stripe dynamics in trilayer nickelate La $_{4}$ Ni $_{3}$ O $_{10}$

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…

Topochemical Fluorination of La $_{2}$ NiO $_{4 + I^´}$ 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…

Terahertz light driven coherent excitation of a zone-folded Raman-active phonon mode in the Spin-Ladder System $I^\pm^{'}$ -NaV $_{2}$ O $_{5}$

Flavio Giorgianni, Martina Romani, Pascal Puphal +5

We investigate the out-of-equilibrium lattice dynamics in the spin-ladder system $I^\pm^{'}$ -NaV $_{2}$ O $_{5}$ using intense terahertz (THz) pump and near-infrared (NIR) probe spectroscopy. W…

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…

Exploring Low-Dimensional Magnetism in Cobalt Vanadates, $A$ CoV $_{2}$ O $_{7}$ ~( $A$ ~=~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 $^{2 +}$ ions, using the optical floating zone m…
