Reversed Crystal Growth

Crystals, 2018
In the last decade, a reversed growth route has been found in many crystal growth processes. In these systems, a single crystal does not develop from a single nucleus.

Three-dimensional nanostructure determination from a large diffraction data set recorded using scanning electron nanodiffraction

IUCrJ, 2016
A diffraction-based technique is developed for the determination of three-dimensional nanostructures. The technique employs high-resolution and low-dose scanning electron nanodiffraction (SEND) to acquire three-dimensional diffraction patterns, with the ...

Magneto-optical imaging of magnetic deflagration in Mn12-Acetate [PDF]

, 2008
For the first time, the morphology and dynamics of spin avalanches in Mn12-Acetate crystals using magneto-optical imaging has been explored. We observe an inhomogeneous relaxation of the magnetization, the spins reversing first at one edge of the crystal
