Description

In recent days, magnetic materials, structures, and devices are getting more popular,
especially those related to spintronics. Research and development of such magnetic
samples require a way to observe magnetization with good spatial and temporal
resolution. Most dynamic changes of magnetization are realized in nanoseconds or even
faster. If we can detect these dynamic processes, we can reveal many exciting
magnetization features and add the fourth dimension to our experiments. We introduce a
scanning Kerr microscope working in two modes: static and dynamic. In static mode, our
microscope detects a direction of magnetization in a variable magnetic field. In dynamic
mode, we use a pump-probe method to reach a temporal resolution and observe a fast
evolution of magnetization.
