标题： Role of non-reciprocity in spin-wave channeling

摘要： 非互易波在任意方向上传播的程度是一个有趣的问题。 我们通过研究合成反铁磁体构成的狭窄物理通道中的声自旋波传播，来探讨这个问题的一个方面。 通过布里渊光散射显微镜和建模的结合，我们证明了即使在尝试沿材料的互易方向引导波时，系统仍然表现出强烈的非互易性特征。 这包括在与预期导引方向垂直的方向上激发高波矢波，以及在既不与物理通道对齐也不与磁性性质的对称轴对齐的方向上传递能量。 这些发现对非互易材料中传播波谱的建模及其潜在应用具有重要意义。 显示英文摘要

摘要： The extent to which non-reciprocal waves can be guided in arbitrary directions is an interesting question. We address one aspect of this problem by studying the propagation of acoustic spin waves in a narrow physical conduit made of a synthetic antiferromagnet. Through a combination of Brillouin Light Scattering microscopy and modeling, we demonstrate that even when attempting to guide waves in the reciprocal direction of the material, the system still exhibits strong signatures of non-reciprocity. This includes the excitation of high wavevector waves in the direction perpendicular to the intended channeling, as well as energy transfer in directions that often neither aligns with the physical conduit nor with the symmetry axes of the magnetic properties. These findings have implications for the modeling of propagating wave spectroscopy in non-reciprocal materials and their potential applications.
