We use phenomenological symmetry arguments to demonstrate that while chiral magnetic (Dzyaloshinskii-Moriya) interactions are conventionally restricted by symmetry to appear in a limited set of noncentrosymmetric materials, they may arise in a material with any symmetry when coupled to a strain field. We derive point-group specific free-energy functionals that capture the relationship between an applied strain field and chiral magnetic couplings, demonstrating how strain may offer highly selective control over magnetic textures. Finally, we discuss several examples of common strain configurations that may lead to out-of-plane modulation in the magnetic moment of a quasi-two-dimensional film as required for applications in magnetic devices.
