On Tensor Distinction of Non-Ferroelastic Domains

Abstract

We show that for any two non-ferroelastic domains arising in a phase transition, it is always possible to find a coordinate system in which the two domains can be distinguished by the sign of a spontaneous component of a property-tensor. Application of these general results is illustrated by an example which shows possible optical distinction of non-ferroelastic domains.
