(a) XMLD-PEEM image in a single T domain. Three S domains, S1, S2, and S3, are observed. (b) Line profile of the solid line shown in (a). This corresponds to the contrast along S1 to S2 to S3. (c) Spin structures estimated from the contrast in (a). The spin axes gradually change from S1 to S2 to S3.
