跟踪状态及其可观测性的时间相关性，即时间分辨测量，是理解系统物理原理的方法之一。在这个视角下，我们回顾了在脉冲强磁场中进行的一些时间分辨测量，其中脉冲磁场的持续时间限制了可用的测量时间尺度，从几毫秒到几百毫秒。我们提供了一些成功的例子，重点介绍了最近在测量和磁场产生技术方面的技术突破。这些实验技术还可以用于其他实验条件，以提高时间分辨测量的信噪比和重复率。考虑到这些应用对当前凝聚态研究的影响，我们还讨论了脉冲磁场中时间分辨测量的未来方向。
Tracking the time-dependence of a state and its observable, i.e., time-resolved measurement, is one of the ways of understanding physical principles of the system. In this Perspective, we review some of the time-resolved measurements performed in pulsed high magnetic fields, where the duration of the pulsed field restricts the available measurement timescale from a few to several hundred milliseconds. We present some successful examples with a focus on the recent technical breakthroughs both in the measurement and magnetic-field generation techniques. These experimental techniques can be used in other experimental conditions in order to increase the signal-to-noise ratio and the repetition rate of time-resolved measurements. Taking the impacts of these applications on current condensed matter research into consideration, we also discuss the future direction of the time-resolved measurement in pulsed magnetic fields.
