Tensor properties discriminating domain walls from non-ferroelastic domains

Abstract

We present a summary of systematic analysis of tensor properties that distinguish non-ferroelastic domain walls from bulk structures (domain states) of adhering domains. In the overwhelming majority of cases domain walls exhibit other (usually richer) tensor properties than domain states. Tables summarizing the results are supplied with numbers of concrete phase transitions (listed in the database of P. E. Tomaszewski, Phase Transitions, 38, 127–220 (1992)) with non-ferroelastic phases in which particular domain walls can appear.

Key Words:

• non-ferroelastic domain walls
• symmetry of domain walls
• tensor properties of domain walls
• pyroelectric domain walls
