Efficient generation and manipulation of magnetic skyrmions are crucial for spintronic applications. This paper experimentally demonstrates the ordered generation of magnetic skyrmions using surface acoustic waves (SAWs) in a [Co/Pd] multilayer integrated into a SAW delay line. The SAWs provide both strain and thermal effects, leading to current-induced skyrmion movement with negligible skyrmion Hall effect (SkHE). This is attributed to energy redistribution within the system due to SAW excitation. The findings offer a new perspective for manipulating topological solitons in skyrmionics and spin acousto-electronics.
