In magnetism, Dzyaloshinskii-Moriya (DM) interaction is one of the important consequences of such structural symmetry, which link to varieties of rich chiral magnetic orders. For a new paradigm in magnetism and spintronics, it is crucial to have control on the DM interaction as well as ordering of the DM vectors which characterize the DM interaction. In this work, we report on a strong interlayer DM interaction emerged in magnetic superlattices whose structural symmetry is unambiguously broken by using the unprecedented technique of our "alternating" stress mechanism.
