Abstract :
Dynamic domain observations have been made using a high-magnification Kerr microscope in combination with a high-speed light-intensified CMOS camera. Results have demonstrated nonrepeatable domain wall motion in electrical steel and amorphous ribbon at 1- and 50-Hz magnetizing frequencies.
