UTe: a narrow band superconductor
Martin Sundermann, Takaki Okauchi, Naoki Ito +10
We investigate the nature of the 5 electrons in the unconventional odd-parity superconductor UTe, focusing on the degree of covalency, localization versus itinerancy, and do…
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…
Magnetic Dichroism in Rutile NiF: Separating Altermagnetic and Ferromagnetic Effects
A. Hariki, K. Sakurai, T. Okauchi +1
We present numerical simulations of x-ray magnetic circular dichroism (XMCD) at the L edge of Ni in the weakly ferromagnetic altermagnet NiF. Our results predict a sign…
