Figure 4
Spectro-ptychography and XMCD of permalloy nanorods. (a) Ptychography amplitude image of permalloy nanorods measured at 706 eV using CL polarized X-rays. The white dotted circles indicate gaps between the nanorods in the range 20–30 nm. The yellow `X' marks the region where the DI presented in Fig. S6 was measured. (b) Ptychography phase image of the same area as in (a). (c) XMCD image of the nanorods with contrast in the range ±0.15. The scale bars in (a)–(c) correspond to 500 nm. (d) Magnified image of the termination of the nanorod, located in the white dotted circle in (c). (e) Surface plot of (d) with color scale indicating the local XMCD at the termination of the nanorod. The x and y axes in the grid line correspond to the length and width of the nanorod, respectively, and the z axis represents the XMCD value. The yellow double-headed arrows in (d) and (e) correspond to the width of the nanorod which is 140 nm.
