Valency, charge-transfer, and orbital-dependent correlation in bilayer nickelates Nd3Ni2O7

Daisuke Takegami, Takaki Okauchi, Edgar Abarca Morales +14

We examine the bulk electronic structure of Nd3Ni2O7 using Ni 2p core-level hard x-ray photoemission spectroscopy combined with density functional theory + dynamical mean-field the…

Circular Dichroism in Resonant Inelastic X-ray Scattering: Probing Altermagnetic Domains in MnTe

D. Takegami, T. Aoyama, T. Okauchi +11

X-ray magnetic circular dichroism provides a means to identify ferromagnetic, chiral, and altermagnetic orders via their time-reversal-symmetry () breaking. However, d…

Gapless dynamic magnetic ground state in the charge-gapped trimer iridate BaNbIrO

Abhisek Bandyopadhyay, S. Lee, D. T. Adroja +18

We present an experimental investigation of the magnetic ground state in BaNbIrO, a fractional valent trimer iridate. X-ray absorption and photoemission spectroscopy…

Quantifying the U covalence and degree of localization in U intermetallics

Andrea Marino, Denise S. Christovam, Daisuke Takegami +17

A procedure for quantifying the U electrons' covalence and degree of localization in U intermetallic compounds is presented. To this end, bulk sensitive hard and soft x-ray ph…

Novel quantum spin liquid ground state in the trimer rhodate BaNbRhO

Abhisek Bandyopadhyay, S. Lee, D. T. Adroja +14

Frustrated magnets offer a plethora of exotic magnetic ground states, including quantum spin liquids (QSLs), in which enhanced quantum fluctuations prevent a long-range magnetic or…

Linear dichroic x-ray absorption response of Ti-Ti dimers along the axis in TiO upon Mg substitution

M. Okawa, D. Takegami, D. S. Christovam +9

Corundum oxide TiO shows the metal-insulator transition around 400-600 K accompanying the nearest Ti-Ti bond ( singlet state) formation along th…

Spectroscopic evidence of Kondo-induced quasi-quartet in CeRhAs

Denise S. Christovam, Miguel Ferreira-Carvalho, Andrea Marino +13

CeRhAs is a new multiphase superconductor with strong suggestions for an additional itinerant multipolar ordered phase. The modeling of the low temperature properties of th…
