TL;DR: It is shown that a pair of coupled skyrmions of opposite chiralities can be stabilized in a symmetric magnetic bilayer system by combining Dzyaloshinskii–Moriya interaction (DMI) and dipolar coupling effects and this results set the ground for emerging spintronic technologies where issues concerningSkyrmion stability, nucleation and propagation are paramount.

TL;DR: A 130% variation of DMI with electric field in Ta/FeCoB/TaO x trilayer is demonstrated through Brillouin Light Spectroscopy through BLS, establishing an additional degree of control to engineer programmable skyrmion-based memory or logic devices.
