摘要：
The three-dimensional (3-D) multiferroic domain patterns in multiferroic rare-earth manganites of the ab-plane cycloidal spin (CS) order and bc-plane CS order are investigated by means of Monte Carlo simulation based on the multiferroic Heisenberg model and phase-field simulation based on the time-dependent Ginzburg-Landau equation. It is revealed that the ferroelectric domains associated with both the ab-plane CS order and bc-plane CS order align in the 180 degrees-domain pattern with polarization parallel with domain walls. The mechanism dominating the domain patterns is discussed.
