X-ray magnetic critical scattering

X-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...

X-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...

Magnetic Small Angle X-Ray Scattering

We present first experimental results of the extension of X-ray Magnetic Circular Dichroism (X-MCD) to Small Angle X-ray Scattering (SAXS). The purpose of this study is to determine size distributions and correlations lengths in the nanometer range of magnetic precipitates in granular systems. Magnetic scattering curves obtained with a GdFe system at the Gd La edge are compared with reference m...

Magnetic Resonant Inelastic X-ray Scattering

Soft x-ray coherent magnetic scattering experiments

The increased coherence of third generation synchrotron sources allows us to port laser techniques such as holography and dynamical light scattering from the visible to the x-ray spectral range. In addition to the obvious improvement in resolution, the x-ray range may allow for new variants that are not possible in the visible, as exemplified by techniques that use the strong magnetic contrast ...
