Surface acoustic waves (SAWs) have emerged as an efficient approach for the acoustic manipulation of magnetization and the generation of spin currents, attracting significant attention in spintronics. In this work, we systematically investigate the magnetotransport properties of a lithium niobate/nickel (LiNbO 3 /Ni) device under nonresonant SAW excitation using time‐resolved electrical measurements. The time‐resolved SAW‐induced voltage is measured as a function of delay time, external magnetic field magnitude, and magnetic field orientation. The SAW‐induced voltage exhibits pronounced magnetization‐dependent modulation, characterized by a double‐valley structure with two valleys appearing near zero magnetic field and the magnetization switching field during magnetic field sweeps and a fourfold angular dependence. These features differ markedly from the single switching‐related feature and twofold angular dependence expected for the conventional anisotropic magnetoresistance effect (AMR). We attribute the SAW‐induced response to dynamic strain‐mediated magnetoelastic coupling, which modulates the magnetization configuration and spin‐dependent scattering in the Ni film. Our results demonstrate a feasible route for using SAWs to probe and control strain‐mediated spin–lattice interactions in magnetic thin‐film devices.
