Magneto-optic Imaging Film Images

Caption

NIST MOIF (Magneto-optic imaging film) technique is unique in being able to image magnetic domains in real time while they are forming, growing and disappearing. Bright and dark regions represent stray magnetic fields as domains change. Here a series of MOIF images shows reversal of domains in a ferromagnetic film having a grid of antiferromagnetic strips on top as the external field increases to the right.
