Magnetic circular dichroism in hard x-ray Raman scattering as a probe of local spin polarization
Manabu Takahashi, Nozomu Hiraoka
We argue that the magnetic circular dichroism (MCD) of the hard x-ray Raman scattering (XRS) could be used as an element selective probe of local spin polarization. The magnitude o…
Resonant x-ray scattering from chiral materials, -quartz and -berlinite
Jun-ichi Igarashi, Manabu Takahashi
We study the resonant x-ray scattering at Si and Al K-edges from chiral materials, -quartz and -berlinite. We derive the general form of the scattering matrix for the dipole…
Ab initio study of 2p-core level x-ray photoemission spectra in ferromagnetic transition metals
Manabu Takahashi, Jun-ichi Igarashi
We study the 2p-core level x-ray photoemission spectra in ferromagnetic transition metals, Fe, Co, and Ni using a recently developed ab initio method.The excited final states are s…
An ab initio study of 3s core-level x-ray photoemission spectra in transition metals
Manabu Takahashi, Jun-ichi Igarashi
We calculate the - and -core-level x-ray photoemission spectroscopy (XPS) spectra in the ferromagnetic and nonmagnetic transition metals by developing an \emph{ab initio} m…
Charge Excitations in Cuprate and Nickelate in Resonant Inelastic X-Ray Scattering
Manabu Takahashi, Junichi Igarashi, Taeko Semba
We analyze the resonant inelastic x-ray scattering (RIXS) spectra at the Cu and Ni K edges in La2CuO4 and La2NiO4, respectively. We make use of the Keldysh-Green-function formalism…
An ab-initio calculation of the core-level x-ray photoemission spectra -Fe 3s- and 1s-core levels-
Manabu Takahashi, Jun-ichi Igarashi, Noriaki Hamada
We develop a method of the ab-initio calculation for the core-level x-ray photoemission spectroscopy (XPS). By calculating one-electron states in the presence of core-hole potentia…
