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…
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…
4p states and X-Ray Spectroscopy
Jun-ichi Igarashi, Manabu Takahashi
The 4p states in transition metals and their compounds usually play minor roles on their physical quantities. Recent development of resonant x-ray scattering (RXS) at the K-edge of…
Resonant magnetic X-ray scattering spectra in SDW Cr -- ab initio study -----
Manabu Takahashi, Jun-ichi Igarashi, Kunitomo Hirai
Using ab-initio band structure calculation based on the local density approximation, Cr K-edge resonant X-ray magnetic scattering spectra are analyzed in the spin density wave (SDW…
X-Ray Magnetic Circular Dichroism at the K edge of Mn3GaC
Manabu Takahashi, Jun-ichi Igarashi
We theoretically investigate the origin of the x-ray magnetic circular dichroism (XMCD) spectra at the K edges of Mn and Ga in the ferromagnetic phase of Mn3GaC on the basis of an…
