Universal crystal classification system Point Symmetry-Physical Property

A diagram showing the relationships between point symmetry and a set of physical properties has been created for centrosymmetric (CS) and noncentrosymmetric (NCS) crystals. The acentric (ferro-, pyro- and piezoelectrical, electrooptical, nonlinear optical, ferromagnetic, enantiomorphic, girotropic),ferroelastic,ferromagnetic and refractive characteristics are accounted. The distribution of crystals over symmetry classes are plotted for CS and NCS elements and their oxides. This diagram is helpful for classification and searching new materials.
