Fig. 2: Development of magnetic structures in the Co8.5Zn7.5Mn4(110) thin film with t ~50 nm.
A series of underfocused LTEM images (defocus value Δf = −2 mm) obtained at 330 K and 0 mT (a), 155 mT (b), 160 mT (c), 170 mT (d), 185 mT (e), and 205 mT (f). The magnetic field was applied perpendicular to the thin film plane. The scale bars are 1 μm. The strong dark line contrasts (the so-called bend contours) seen in the upper left to lower middle of each figure appear at locations where the Bragg condition is locally satisfied due to sample bending. Further details are displayed in Supplementary Figs. 1, 2. The blue dotted box in d corresponds to Fig. 3a.
