Incipient magnetic instability in RuO with random phase approximation
Diana Csontosová, Kyo-Hoon Ahn, Jan Kuneš
We study the instability in RuO using the Hartree-Fock approximation followed by the random phase approximation. We employ a three-orbital Hubbard model without spin-orbit coup…
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…
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…
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…
Theory of circular dichroism in resonant inelastic x-ray scattering
M. Furo, A. Hariki, J. Kuneš
We analyze circular dichroism (CD) in resonant inelastic x-ray scattering (RIXS) in magnetic materials. We define RIXS-CD as the difference between scattering amplitudes for the ri…
