Abstract :
We use a new method for visualization and direct experimental study of dynamic magnetization processes and for nondestructive characterization of the defect structure of magnetic multilayers. The method utilizes a transparent indicator ferrimagnetic magneto-optic film with in-plane anisotropy. An example of its application to the investigation of the magnetization reversal by domain wall motion in electrochemically produced CoNiCu/Cu multilayers which exhibit a giant magnetoresistance effect is described
