Stabilization of magnetic skyrmions. a–f Spin-polarized dI/dU maps of the same area taken with out-of-plane magnetic fields as indicated (I = 1 nA, U = −400 mV, ΔUrms = 40 mV, scale bar is 50 nm). g–i Magnified dI/dU maps recorded on the same skyrmion with an out-of-plane (g), in-plane (h), and non (i) spin-polarized tip (I = 1 nA, U = −400 mV for g and h and −200 mV for i, ΔUrms = 40 mV for g and h and 30 mV for i, scale bar is 10 nm)
