The fantastic ferroelectric response to the magnetic field observed in Ca(3)CoMnO(6) compound, where the ferroelectricity is driven by the collinear magnetism, is investigated by using Monte Carlo simulation based on a one-dimensional elastic Ising model. The microscopic domain structures of spins and ionic displacements are evaluated at different temperatures under different external magnetic fields. It is revealed that the up-up-down-down (up arrow up arrow down arrow down arrow) spin domains clamped with the domains of ionic displacement are responsible for the exotic ferroelectric behavior upon different magnetic fields in the low temperature range.
