International Tables for Crystallography are no longer available for purchase from Springer. For further information please contact Wiley Inc. International Tables for Crystallography Volume D: Physical Properties of Crystals is concerned with the influence of symmetry on the physical and tensor properties of crystals and on their structural phase transitions. This role is very important in many different disciplines of the science of materials such as crystallography, elasticity, solid-state physics, magnetism, optics, ferroelectricity and mineralogy.
