Spin-wave-assisted switching (SWAS), a method that achieves magnetization switching at a significantly reduced magnetic field (H_sw) by exciting the spin wave dynamics, is a promising technique for data storage of spin-based wave parallel computing. In this study, we conducted SWAS experiments employing exchange-coupled L1₀-Fe₅₀Pt₅₀ / Ni₈₁Fe₁₉ epitaxial thin films, and examined the selective switching conditions by modifying the shape of the element and/or the thickness of the soft magnetic Ni₈₁Fe₁₉ layer.
