Quadrupolar magnetic excitations in an isotropic spin-1 antiferromagnet

open access: yesNature Communications, 2022
Multipolar magnetic excitations are challenging to measure as most experimental probes are sensitive to dipolar processes. Here, Nag et al. show the existence of dispersing quadrupolar components to the spin excitations in an antiferromagnet ...

A comparison of an electron diffraction and an X-ray diffraction experiment from a single protein microcrystal lamella [PDF]

open access: yesStructural Dynamics
X-ray diffraction (XRD) of microcrystals is signal-to-noise limited by the inherently weak diffraction. As such, Electron diffraction (ED) is increasingly used to measure diffraction data from submicron crystals, or those deemed too small for XRD due the
