Probing La-based nickelates with Ni 1 core-level photoelectron spectroscopy

Daisuke Takegami, Naoki Ito, Koto Fujinuma +15

We present a comparative Ni core level photoemission study of LaNiO, NdNiO, and LaNiO using both the Ni and the Ni . We address the challenges…

Bi-altermagnetism unveiled by sublattice-specific circular dichroism in resonant inelastic X-ray scattering

G. Channagowdra, A. Singh, H. Y. Huang +9

An altermagnet is a recently identified class of magnets that exhibit a zero net magnetic moment but break symmetry under the combined operations of parity and time reversal. It ty…

UCd: A strongly localized 5 material

Martin Sundermann, Naoki Ito, Daisuke Takegami +11

UCd is an antiferromagnetic uranium intermetallic compound ( = 5.3K) with enhanced electron mass and uranium-uranium spacings nearly twice the Hill limit, suggest…

Nanoscale imaging of spin textures with locally varying altermagnetic response in -FeO

R. Yamamoto, S. Mayr, A. Hariki +20

Altermagnetism is a recently identified magnetic state in which time-reversal symmetry is broken despite a collinear compensated spin structure. The response of altermagnets is det…

X-ray magnetic circular dichroism evidence of intrinsic -wave altermagnetism in rutile-structure NiF

Zezhong Li, Kosuke Sakurai, Yiu-Fung Chiu +13

We present the x-ray magnetic circular dichroism (XMCD) at the Ni -edge as an evidence of the -wave altermagnetism in rutile-structure NiF. Sizable XMCD signal is o…

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…
