Finding new energy-efficient methods for exciting magnetization dynamics isone of the key challenges in magnonics. In this work, we present an approach toexcite the gyrotropic dynamics of magnetic vortices through the phenomenon ofinverse magnetostriction, also known as the Villari effect. We develop ananalytical model based on the Thiele formalism that describes the gyrotropicmotion of the vortex core including the energy contributions due to inversemagnetostriction. Based on this model, we predict excitations of the vortexcore resonances by surface acoustic waves whose frequency is resonant with thefrequency of the vortex core. We verify the model's prediction usingmicromagnetic simulations, and show the dependence of the vortex core'soscillation radius on the surface acoustic wave amplitude and the static biasfield. Our study contributes to the advancement of energy-efficient magneticexcitations by relying on voltage-induced driven dynamics, which is analternative to conventional current-induced excitations.
