From: Observation of switchable polar skyrmion bubbles down to the atomic layers in van der Waals ferroelectric CuInP2S6

Fig. 4

a, b, Topographic and PFM mappings demonstrating electrically switchable elongated and circular polar skyrmions under different DC biases. c Evolution of the dipolar configuration realized by continuous PFM scanning with an estimated force of −30 nN over 6 times. d Schematics of the transition between different skyrmionic states. The helicity number is switched between 0 and π.
