Tensorial classification of non-magnetic ferroic crystals

A group-theoretical method is presented to determine the tensorial classification of ferroic crystals with respect to an arbitrary macroscopic tensorial property. This method is used to derive tables of the tensorial classification in the special case where the components of the tensorial property transform as a single irreducible representation of the prototypic point group. It is also shown how these tables facilitate implementation of this method in the general case. Examples are given of the application of this method and the use of these tables in determining the tensorial classification of ferroeleetric and gyrotropie ferroic crystals.
