Strain manipulation of the magnetic domains, such as the stripe domains andskyrmions, has attracted considerable attention because of its potentialapplications for magnetic logic and memory devices. Here, utilizing phase-fieldmodeling, we demonstrate the deterministic modulation of the orientation andthe configuration of the stripe domains and skyrmions by using a uniaxialstrain. The reorientation of the stripe domains can be caused by a suitablestrain, and the direction of the reorientated domains is determined by thedirection of the applied uniaxial strain and the type of domain walls,including Bloch- and N\'eel- types. Furthermore, by constructing a phasediagram, we discovered that when the uniaxial tensile strain increases, theferromagnetic islands undergo a continuous phase transition from a skyrmion tomulti-domains or a single domain. The competition between magnetic anisotropyenergy and stray field energy leads to the continuous phase transition and theformation of domain patterns under the uniaxial tensile strain. Our researchprovides a theoretical foundation for the development of strain-controlledmagnetic domain designs.
