论文摘要
我们报告在55 nm薄的Yig中单向旋转波梁的单向传输。我们降低了一种手性耦合技术，该技术实现了具有不同宽度和晶格间距的NI80FE20纳米线阵列，以研究向下到lambda = 80 nm的交换旋转波的非重新传播。这些高波形耦合模式的完整自旋波光谱分析显示，由于耦合效率的非单调场依赖性以及来自纳米线的非外观散射场的非单调场依赖性，因此表征了它们的传播特性。
We report unidirectional transmission of micron-wide spin waves beams in a 55 nm thin YIG. We downscaled a chiral coupling technique implementing Ni80Fe20 nanowires arrays with different widths and lattice spacing to study the non-reciprocal transmission of exchange spin waves down to lambda = 80 nm. A full spin wave spectroscopy analysis of these high wavevector coupled-modes shows some difficulties to characterize their propagation properties, due to both the non-monotonous field dependence of the coupling efficiency, and also the inhomogeneous stray field from the nanowires.
