We investigate the temporal response of constriction-based spin Hall nano-oscillators driven by pulsed stimuli using time-resolved Brillouin light scattering microscopy. The growth rate of the magnetization auto-oscillations, enabled by spin Hall effect and spin orbit torque, is found to vary with the amplitude of the input voltage pulses, as well as the synchronization frequency set by an external microwave input. The combination of voltage and microwave pulses allows to generate auto-oscillation signals with multi-level amplitude and frequency in the time-domain. Our findings suggest that the lead time of processes such as synchronization and logic using spin Hall nano-oscillators can be reduced to the nanosecond time-scale.投稿至《物理评论应用》（Physical Review Applied）的论文《自旋霍尔纳米振荡器的响应敏捷性》的数据存储库。本次重投稿的数据指纹：MD5值为a9bbd503a5370963b835d3c40cdf8ba8。请忽略旧版本数据的MD5值：36e53eb278f8c3073a51de6c709f72c8。（请忽略MD5值3e2ddf76473149ad1d58cf100f90321f，该值来自未完成的投稿，我无法移除该标记）。 数据按单幅图表逐一整理。本次提供的《数据浏览指南》文件关联了每幅图表所用到的全部数据集与数据处理脚本。数据处理环节采用了IPython Notebook（Ipython notebook），子图组装与绘图标注则通过Omnigraffle完成。对应图表中的实验数据可在与图表命名一致的.txt格式文件中获取。 摘要：本研究利用时间分辨布里渊光散射显微镜（time-resolved Brillouin light scattering microscopy），研究了脉冲激励下基于缩颈结构的自旋霍尔纳米振荡器（spin Hall nano-oscillators）的时域响应特性。由自旋霍尔效应（spin Hall effect）与自旋轨道力矩（spin orbit torque）驱动的磁化自动振荡的生长速率，会随输入电压脉冲的幅值以及外部微波输入设定的同步频率发生变化。结合电压脉冲与微波脉冲，可在时域生成具备多幅值、多频率特性的自动振荡信号。本研究结果表明，利用自旋霍尔纳米振荡器实现同步与逻辑运算等流程的响应时长可压缩至纳秒级。
