Extended Data Fig. 3: Field Evolution of SK-MTJ and FL Dots.

From: All-electrical skyrmionic magnetic tunnel junction

Extended Data Fig. 3

MFM images of WDot ≃ 300 nm dot arrays (referenced to positively magnetized tip) for (a-b) SK-MTJ, after (a) −1.5 T saturation, and (b) +1.5 T saturation (flipped x-axis for ease-of-comparison), and (c) FL, respectively. Middle insets show colour bars indicating the field evolution of magnetic states: UM ↑,↓ and SK ↑,↓, respectively (c.f. Extended Data Fig. 2).
