Self-consistent aspects of x-ray absorption calculations.
We implemented a self-consistent, real-space x-ray absorption calculation within the FDMNES code. We performed the self-consistency within several schemes and identified which one is the most appropriate. We show a method that allows a rigorous setting of the Fermi level and thus an estimation of the energy cutoff for the identification and elimination of the occupied states. We investigated wh...
متن کاملX-ray Magnetic Absorption and Scattering (XAFS)
1.Introduction In 3rd generation synchrotron radiation (SR), one of the most promising items may be control and characterization of polarization state. In particular, they are a crucial factor to study magnetic properties using the various techniques inscattering, absorption, diffraction and emission experiments. Indeed, low emittance SR such as Spring-8 can efficiently realize this performance...
متن کاملX-Ray Magnetic Absorption and Scattering (XMAS)
1 . Introduction Understanding of magnetic property and structure in magnetic materials forms a wide field of research interesting not only from a fundamental point but also from a practical point. Advantages in brilliance and polarization of 3rd generation synchrotron radiation (SR) open out a new field in magnetism differing from neutron magnetic scattering. In particular, this is characteriz...
متن کاملX-ray scattering and absorption studies of MnAs/GaAs heterostructures
Ferromagnetic MnAs thin films grown on GaAs ~001! substrates by molecular-beam epitaxy have been studied by the methods of grazing incidence x-ray scattering, x-ray diffraction, and extended x-ray-absorption fine structure. Microstructures in two films prepared with different first-layer growth conditions ~template effects! are compared in terms of the interfacial roughness in the layer structu...
متن کاملMultiple-scattering calculations of x-ray-absorption spectra.
A high-order multiple-scattering (MS) approach to the calculation of polarized x-ray-absorption spectra, which includes both x-ray-absorption ne structure (XAFS) and x-ray-absorption near-edge structure (XANES), is presented. EEcient calculations in arbitrary systems are carried out by using a curved-wave MS path formalism that ignores negligible paths, and has an energy-dependent self-energy a...
