It has come to our attention that images of static domain patterns in Permalloy using a quadrant-detection scheme were first obtained by Clegg, Heyes, Hill, and Wright in 1991.12Thus, our claim to have been the first group to image static domains using such a method was incorrect. The description of the instrument and its principle of operation remain correct. The quality of the image presented3represents an improvement over previously published results using a similar detection scheme, permitting an unambiguous determination ofNe´elwall polarity within the imaged domain structures. ©1997 American Institute of Physics.
