Chiral magnets are of fundamental interest and have important technological ramifications. The origin of chiralmagnets lies in the Dzyaloshinskii-Moriya interaction (DMI), an interaction whose experimental and theoreticaldetermination is laborious. We derive an expression that identifies the electric dipole moment as descriptor forthe systematic design of chiral magnetic multilayers. Using density functional theory calculations, we determinethe DMI of (111)-oriented metallic ferromagnetic Z/Co/Pt multilayers of ultrathin films. The nonmagneticlayer Z determines the DMI at the Co-Pt interface. The results validate the electric and magnetic dipolemoments as excellent descriptors. We found a linear relation between the electric dipole moment of Pt, theAllen electronegativity of Z, and the contribution of Pt to the total DMI.
