Topological materials have gained significant attention due to their unique physical properties, including topologically protected edge states that allow for lossless propagation of currents or spin waves. These properties have the potential to impact information storage and transmission technologies. Although topological magnons have been demonstrated in various quantum magnets, direct experimental observation of edge modes remains unachieved. Most proposed topological magnonic crystal structures have been difficult to create experimentally [1, 2]. This study aims to observe chiral edge spin waves in experimentally feasible structures and explore the conditions for realizing and detecting topological edge modes.
