Figure 3.4.2.2

Exploded view of single-domain states $[{\bf S}_1]$ , $[{\bf S}_2]$ , $[{\bf S}_3]$ and $[{\bf S}_4 ]$ (solid rectangles with arrows of spontaneous polarization) formed at a phase transition from a parent phase with symmetry $[G=4_z/m_zm_xm_{xy} ]$ to a ferroic phase with symmetry [F_1=2_xm_ym_z] . The parent phase is represented by a dashed square in the centre with the symmetry elements of the parent group $[G=4_z/m_zm_xm_{xy}]$ shown.
