a AFM images of the La0.325Pr0.3Ca0.375MnO3 (LPCMO) disks with diameter sizes of 500 nm, 1 μm, 2 μm, 3.8 μm, 5 μm, and 7 μm in diameter. b–d MFM images of the LPCMO disks under external magnetic field of 1 T (external magnetic field direction is pointing perpendicularly to the sample surface plane) taken at 10 K (b), 100 K (c), and 180 K (d). The negative value in MFM image indicates attractive force and positive value indicates repulsive force. Reproduced with permission of [106]
