Abstract
The behavior of the ferroelastic DCs in [N(CH3)(4)](2)CuCl4 was investigate d by the measurement of the strain-stress hysteresis loop and of the bias s tress field dependence of DC interaction potential. The ferroelastic double hysteresis loop observed in [N(CH3)(4)](2)CuCl4 suggested the existence of the regularly spaced ferroelastic DCs in the incommensurate phase. The osc illating behavior of the second derivative of the DC interaction energy U(x ) was investigated to discuss the energy minimized positions of the ferroel astic DCs.
