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…
