Redetermination of the crystal structure of K[BrF4] from single-crystal X-ray diffraction data

IUCrData, 2018
Single crystals of K[BrF4], potassium tetrafluoridobromate(III), were grown from a solution of KHF2 in bromine trifluoride. The current report is the first refinement of the crystal structure of K[BrF4] using single-crystal X-ray diffraction data.

Ultrafast X-ray diffraction probe of terahertz field-driven soft mode dynamics in SrTiO3

Structural Dynamics, 2017
We use ultrafast X-ray pulses to characterize the lattice response of SrTiO3 when driven by strong terahertz fields. We observe transient changes in the diffraction intensity with a delayed onset with respect to the driving field ...

Watching ultrafast responses of structure and magnetism in condensed matter with momentum-resolved probes

Structural Dynamics, 2017
We present a non-comprehensive review of some representative experimental studies in crystalline condensed matter systems where the effects of intense ultrashort light pulses are probed using x-ray diffraction and photoelectron spectroscopy.
