Picometer polar atomic displacements in strontium titanate determined by resonant X-ray diffraction [PDF]
Nature Communications, 2018 It is a challenge to measure changes in the crystal structures in picometer scale and the associated phase. Here the authors demonstrate the lattice expansion and polar distortions of oxygen deficient SrTiO3 using a resonance X-ray scattering technique.

On the power and promise of resonant diffraction for powders [PDF]
Structural DynamicsSignificantly more information is available if X-ray scattering and spectroscopic techniques are combined. In crystallography, structural information is encoded in the intensity of Bragg peaks, with the complex scattering power of each atom given by f(Q ...

Resonant X‐Ray Diffraction of Conjugated Polymers at the Selenium K‐Edge [PDF]
Macromolecular Rapid CommunicationsABSTRACT Conjugated polymers exhibit a rich microstructure with a degree of order between amorphous and crystalline. The performance of semiconductor devices based on conjugated polymers is strongly influenced by this microstructure yet it is difficult to fully characterize. This work investigates the potential of

Altermagnetism and chiral order in a collinear antiferromagnet (MnF2) [PDF]
Scientific ReportsIn this work, we study hitherto unknown magnetic properties of a collinear antiferromagnet of widespread interest, because there is intense speculation that the compound is a good atomic altermagnet with spin split electronic bands (manganese fluoride ...

Resonant X-Ray Diffraction Studies on the Charge Ordering in Magnetite [PDF]
Physical Review Letters, 2006 Here we show that the low temperature phase of magnetite is associated with an effective, although fractional, ordering of the charge. Evidence and a quantitative evaluation of the atomic charges are achieved by using resonant x-ray diffraction (RXD) experiments whose results are further analyzed with the help of ab initio calculations of the ...

X-ray magnetic diffraction under high pressure
IUCrJ, 2019 Advances in both non-resonant and resonant X-ray magnetic diffraction since the 1980s have provided researchers with a powerful tool for exploring the spin, orbital and ion degrees of freedom in magnetic solids, as well as parsing their interplay.

Data on the effect of NbC inoculants on the elastic and microstructural evolution of LBP-DED IN718
Data in Brief, 2023 The use of inoculants added to precursor powder is a method of influencing grain growth during fabrication. Niobium carbide (NbC) particles have been added to IN718 gas atomised powder for additive manufacturing via laser-blown-powder directed-energy ...
