Fig. 3: Magnetic field dependent sMIM imaging.
From: Direct visualization of edge state in even-layer MnBi2Te4 at zero magnetic field
a Magnetic field dependent sMIM images at +40 V gate voltage. The scale bar is 3 μm. b Field dependent sMIM bulk signals extracted from Fig. 3a. The signal is averaged over the sample interior. Also plotted is the measured bulk current from transport (red solid line).
