Physical properties of material are dependent on constituent atoms and crystal structure. They vary depending on external conditions, such as temperature and pressure. Our main aim is to demonstrate relationships between crystal structures and physical properties. Structure and dynamics are studied by means of x-ray diffraction, diffuse scattering, inelastic scattering, and magnetic scattering. We measure physical properties at low- and high-temperature, in magnetic fields, and under hydrostatic pressure to examine characteristics of material and to explore new phenomena.
