Abstract:Neutron diffraction has long history of application in condensed matter physics, solid state chemistry, and materials science. Sensitivity to positions of light elements (e.g. H, Li, Na) in the presence of heavy elements allows neutrons to provide information which cannot be obtained with X-rays. Sensitivity to magnetic moments of atoms makes neutron diffraction the main tool for magnetic structure determination. Finally, high penetrating power of centimeter size neutron beams enables non-destructive analysis of bulk samples often under conditions similar to real life environment. I will present the capabilities of neutron diffraction with examples of the studies of functional materials.

Short bio:Max Avdeev is responsible for the high-resolution neutron powder diffractometer at the OPAL research reactor operated by the Australian Nuclear Science and Technology Organisation (ANSTO).

He received PhD in 1999 for the work in synthesis and crystal structural studies of Na-superionic conductors. After postdoctoral position at the Argonne National Laboratory (USA), in 2005 he joined ANSTO as a full-time researcher. He also holds Adjunct Professor position at the University of Sydney.

His main research interests are studies of crystal and magnetic structure of inorganic materials using X-ray and neutron diffraction and atomistic modelling. The results were published in over 350 papers in condensed matter physics, solid state chemistry, and materials science journals.
