| アブストラクト: |
Even very recently, a lot of problems in chemistry and physics requesting precise structural investigations by neutron scattering, were out of reach, especially when only very small samples were available or when a very systematic study e.g. versus an external control parameter such as temperature, was needed, in both cases because too highly prohibitive in beamtime. Henceforth, work with small single crystals, rapid crystallography or reciprocal space surveying are possible thanks to the recent developments of neutron Laue diffraction and in particular to instruments like VIVALDI at the Institut Laue-Langevin. After a brief presentation of this class of neutron diffraction instruments, several topical examples on magnetic structure determination, photomagnetic commutation and related structural modifications or on the latest chemical trends will be presented.
