On the Néel Vector Dependence of X-ray Magnetic Circular Dichroism in Altermagnets
Jan Kuneš
Dependence of x-ray magnetic circular dichroism on the experimental geometry is described by a frequency-dependent Hall vector. Using group theory, we derive a general relationship…
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…
Determination of the Néel vector in rutile altermagnets through x-ray magnetic circular dichroism: the case of MnF
A. Hariki, T. Okauchi, Y. Takahashi +1
We present a numerical simulation of the X-ray magnetic circular dichroism (XMCD) at the edge of Mn in altermagnetic MnF using a combination of density functional + e…
Fingerprints of Mott and Slater gaps in the core-level photoemission spectra of antiferromagnetic iridates
K. Nakagawa, A. Hariki, T. Okauchi +15
We present Ir core-level hard-x-ray photoemission spectroscopy (HAXPES) experiments conducted across antiferromagnetic (AFM) ordering transition in Ruddlesden-Popper iridates…
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…
Metal-insulator transition in CaCuFeO
Atsushi Hariki, Tatsuya Yamaguchi, Mathias Winder +1
We study structurally-triggered metal-insulator transition in CaCuFeO by means of local density approximation (LDA) + and LDA+dynamical mean-field theory (DMFT).…
Theoretical investigation of excitonic magnetism in LaSrCoO
J. Fernández Afonso, A. Sotnikov, J. Kuneš
We use the LDA+U approach to search for possible ordered ground states of LaSrCoO. We find a staggered arrangement of magnetic multipoles to be stable over a broad range of Co…
