    • In our standard Metropolis MC simulations, we consider a conventional cubic cell with 16 spin sites. For one MC simulation, we first generate a random spin configuration. Then we decrease the system temperature from 100 to 0.1 K gradually. We repeat several MC simulations to confirm the spin ground state obtained from our MC simulations. If we do not include the single-ion anisotropy and the effect of the DM interaction, the ground state is a perfect isotropic ferromagnetic state. If we include only the DM interaction, the ground state is the same because of the collinearity of the state.
