"Neutron diffraction in condensed matter research"
V. A. Turchenko

The modern level of development of neutron diffractometers makes it possible to successfully use the unique properties of neutrons to study the crystal and magnetic structure of bulk materials, determine the position of light atoms in the presence of heavy ones, as well as to study structures containing elements with similar atomic numbers. The neutron diffraction method is indispensable for conducting comprehensive research in the field of condensed matter physics, biology, chemistry and materials science. It is used for a detailed study of magnetic ordering in crystals, for determining the magnitude and directions of magnetic moments for specific ions, and also allows us to establish the relationship of structural features of materials depending on environmental conditions (temperature, pressure, magnetic and electric fields). The development of a new high-flux pulsed neutron source, the new-generation reactor NEPTUN, will contribute to further expanding the possibilities of neutron diffraction.
