In this article, uniaxial-stress effects on spin-driven multiferroics and magnetic skyrmion materials are reviewed. In both systems, symmetries of magnetic and crystal structures are closely related to cross-correlated phenomena such as magnetically induced electric polarization and unconventional Hall effect induced by non-coplanar magnetic order. An application of uniaxial stress is one of the most primitive ways to control the symmetry of matter. We have developed uniaxial stress cells, and have demonstrated that the magnetic phase transitions and resulting cross-correlated phenomena in multiferroics and magnetic skyrmion systems can be controlled by applying a relatively weak uniaxial stress.
