Antiphase Domain Boundaries (IMAGE) DOE/Brookhaven National Laboratory Caption These are images of the antiphase domain boundaries (black wavy lines) after the sample was cooled from above a certain temperature. Images (a) through (d) refer to various thermal cycles providing different magnetic domain and wall configurations each time. The blue arrows indicate the position of a stationary structural defect, used as a reference point.
