In-field XCD images at the Dy L\(_3\) edge and deconvolution of XMCD and XNCD images, T = 25 K. (a, b) XCD contrast images collected at T = 25 K and H = ±2 T. Contrast variations are due to chiral texture (XNCD) superimposed on a rather uniform magnetic contrast. (c, d) XMCD and XNCD images obtained by subtraction and addition of XCD images taken with opposite fields, respectively. The chiral domain structure closely resembles the domain pattern collected at 300 K in zero applied field, shown in Fig. 1c. The sign reversal of blue/red chiral domains between the 25 and 300 K images is due to a sign inversion of the XNCD signal for an incident energy that maximizes the XMCD signal.
