Dzyaloshinskii–Moriya interaction
E1017089
antisymmetric exchange interaction
exchange interaction
magnetic interaction
spin–orbit interaction effect
The Dzyaloshinskii–Moriya interaction is an antisymmetric exchange interaction in magnetic systems that favors chiral, non-collinear spin arrangements and underlies phenomena such as skyrmions and chiral domain walls.
