(color online) (a)–(f) Lorentz TEM images for temperature dependence of cross-tie domain wall evolution in amorphous Ce14Fe80B6 ribbon;[61] (c) the enlarged area of red rectangle region of panel (b). The inset of panel (c) shows the corresponding TIE analyzed spin texture of cross-tie wall. Panels (g)–(h) show the schematic spin configuration.[10,62]
