WebIt has been predicted that also in the linear response of non-centrosymmetric media, reciprocity may fail. 13,29–31 The class of non-centrosymmetric materials, i.e. substances without a center of spatial inversion symmetry, includes the class of chiral materials. WebThe Dzyaloshinskii–Moriya interaction (DMI), which only exists in noncentrosymmetric systems, plays an important role in the formation of exotic chiral magnetic states. However, the absence of the DMI occurs in most two-dimensional (2D) magnetic materials due to their intrinsic inversion symmetry. Here, by u
