Neutron single-crystal diffraction is the tool of choice to determine the accurate positions of hydrogen atoms in solids and the arrangements of magnetic moments. Since neutron fluxes are low compared to those available at synchrotron X-ray facilities, there has been a major effort to maximize the exploitation of the available scattering data. To achieve this much emphasis has been recently...
Diffraction techniques (either photons, electrons or neutrons based) are located at the forefront of the characterisation for new materials. Compared to lab-based sources the distinct features of neutrons make neutron diffraction a unique tool for structure investigations in various classes of materials. At the moment, diffraction studies at ambient conditions contain a minor portion of the...
The overwhelming majority of neutron spectroscopic experiments is carried out at non-ambient conditions for diverse reasons ranging from cooling the sample to improve the signal-to-noise ratio over situating the studied system into a precise point on its phase diagram to "playing" with its hamiltonian. The latter case, consisting e.g. in applying magnetic fields to quantum spin systems, calls...
For hard matter samples the sample environment (SE) is covering a huge number of different fields, starting from a simple sample holder for normal ambient conditions to SE used for in situ growth of a thin layer by beam epitaxial growth or pulsed laser deposition. In between is a wild zoo serving all the different scientific investigation on your instrument. In soft matter and biology, it is...
