磁振子学的范例是基于利用传播的自旋波（或其量子磁振子）在磁场控制的设备中进行信号传输和处理。为下一代微电子学实现磁振子器件需要使用微米至纳米尺寸的自旋波引导结构。因此，深入理解微观波导中自旋波的传播、激发和控制是该领域进一步发展的绝对先决条件。在这里，我们回顾了最近的实验自旋波传播的微观磁振子波导利用高分辨率布里渊光散射光谱，使2-D可视化的自旋波在纳米尺度上。
The paradigm of magnonics is based on utilization of propagating spin waves (or their quanta-magnons) for signal transmission and processing in magnetic-field-controlled devices. Implementation of magnonic devices for future-generation microelectronics requires the use of spin-wave guiding structures with micrometer-to nanometer-sized dimensions. Therefore, the deep understanding of propagation, excitation, and control of spin waves in microscopic waveguides is an absolute prerequisite for further developments in the field. Here we review recent experiments on spin-wave propagation in microscopic magnonic waveguides utilizing high-resolution Brillouin light-scattering spectroscopy enabling 2-D visualization of spin waves on the nanoscale.
