Abstract
A discussion on magnetic domain imaging of exchange bias system NiO/Cu/NiFe was presented by Kerr microscopy. Two types of magnetic domain structures with different Cu thickness were observed by Kerr microscopy for the NiO/Cu/NiFe system. The results showed a frozen-in magnetic structure coinciding with domain wall at room temperature at Cu = 8 Å. The domain images expanded with frustrated domain wall instead at Cu = 2 Å.
