a, Optical microscopy image indicating the folded region being studied with a black arrow. b, Three-dimensional height profile map of the folded region in a buffered membrane (type C), shown from the top, obtained using confocal microscopy (Methods). The colour legend indicates the height profile. Scale bar, 20 µm. c, Fe L3-edge X-ray transmission contrast obtained at the right side of the folded membrane, as approximately indicated with a dashed box in b. Our characterization confirmed that the buffered membrane was oriented with the α-Fe2O3 side facing up and the buffer side facing down (Methods). Scale bar, 2 µm. d–f, AFM STXM contrast obtained across different temperatures: \(T > {T}_{{\rm{M}}}^{\;{\rm{FF}}}\) (d), \(T \approx {T}_{{\rm{M}}}^{\;{\rm{FF}}}\) (e) and \(T < {T}_{{\rm{M}}}^{\;{\rm{FF}}}\) (f). The OOP and IP contrasts are indicated in purple and yellow/orange, respectively, as that in Fig. 2. The AFM textures across the folds were mapped out by ‘stitching’ together multiple images, and optimizing the focal point for each corresponding region.
