Description

In today's world, we have access to a vast amount of information, but it's easy to forget how far we've come. Thanks to advancements in magnetometry, we can now detect quantum phenomena at an unprecedented level. Even seemingly "boring" magnets like Permalloy have become exciting when combined with sensitive probes of local magnetic signals. Just take a look at this gorgeous microstructure!There are mainly three types of domains magnetized in different directions on this image: red is magnetized up, blue is magnetized down, and white is not magnetized. While it is a textbook example of the magnetic domains in the ferromagnet, the satisfaction of witnessing this effect at such a level of detail is simply amazing.
