The physical property coefficients that arise in a phase transition which are zero in the high‐symmetry phase and nonzero in the low‐symmetry phase are called spontaneous coefficients . For all 1601 Aizu species of phase transitions, matrices have been constructed which show the nonzero coefficients of a wide variety of magnetic and nonmagnetic physical properties including toroidal property coefficients in the high‐symmetry phase and their corresponding spontaneous coefficients in the low‐symmetry phase. It is also shown that these spontaneous coefficients provide for the distinction of and switching between nonferroelastic domain pairs.
