Neutron diffraction from novel materials

Few recent examples are discussed where neutron diffraction had a major impact in rapidly developing areas of materials science and that illustrate advances in experimental technique and data analysis. Emphasis is put on imaging structural information across a multidimensional parameter space. High-speed diffractometers with low background have enabled impressive structural studies on small samples previously thought to be beyond the capability of neutron diffraction. Precision measurements of structural parameters have provided critical tests of theoretical models for the behavior of novel materials, and extreme sample environments have opened new experimental frontiers. The impact of neutron diffraction on condensed-matter science is highlighted
