The magnetic heterostructures provide flexible ways to realize particular magnetic properties that possess both scientific and practical significance. Here, by first-principles calculation, we predict strong Dzyaloshinskii–Moriya interactions (DMIs) by constructing CrI3/Metal heterostructures. The underlaying mechanisms are ascribed to the large spin-orbital coupling (SOC) of the I atom and the structural distortion in CrI3 layer caused by substrates. This is different from the traditional way that deposit magnetic films on substrate to genera...
