Abstract

<p>Magnetic skyrmions, characterized as topological spin defects, have attracted widespread interest owing to the emergent electrodynamics that promises innovative application in novel spintronic devices. Our novel approach for material design has led to the discovery of the triangular-lattice formation of magnetic skyrmions in rare-earth intermetallics Gd₂PdSi₃. We have identified large amplification of the topological Hall signal, a phenomenon stemming from the confined emergent magnetic fields inherent to densely packed, miniaturized skyrmions. This pioneering development in material design has ignited a fervent quest for new skyrmion-hosting materials in frustrated magnets.</p>
