Abstract
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. 1 2 Thus, 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 presented 3 represents an improvement over previously published results using a similar detection scheme,...
