From: Two-dimensional anion-rich NaCl2 crystal under ambient conditions

Fig. 4

Atomic force microscopy (AFM) images (a, c) and MFM images (b, d) in the same area of Na–Cl@p-GO membrane on the silicon wafer. The MFM tip was magnetized into the Na–Cl@p-GO surface (b) and out of the Na–Cl@p-GO surface (d), respectively.
