Enhanced ultrafast X-ray diffraction by transient resonances

, 2022
Diffraction-before-destruction imaging with single ultrashort X-ray pulses has the potential to visualise non-equilibrium processes, such as chemical reactions, at the nanoscale with sub-femtosecond resolution in the native environment without the need of crystallization.

Coherent Resonant Soft X-ray Scattering Study of Magnetic Textures in FeGe

Quantum Beam Science, 2018
Coherent resonant soft X-ray scattering was utilized to examine the magnetic textures in a thin plate of the cubic B20 compound FeGe. Small-angle scattering patterns were measured with controlled temperatures and magnetic fields exhibiting magnetic ...

Determination of absolute chirality using resonant X-ray diffraction [PDF]

The European Physical Journal Special Topics, 2012
We have demonstrated that resonant diffraction experiments using the circularly polarized X-ray beam absolutely determines the crystal chirality. Both berlinite and quartz crystals belonging to space group P3221 show higher azimuth-constant intensity for the negative (−) helicity beam than that for the the positive (+) helicity beam for space-group ...

Nonlinear reversal of photoexcitation on the attosecond time scale improves ultrafast X-ray diffraction images

Nature Communications
The complex refractive index of a material governs its light-matter interactions, with intense light fields enabling tailored nonlinear optical responses. In the X-ray regime, rapid photoionization limits the potential of nonlinear techniques by inducing
