TL;DR: In this article, the authors investigate the Dzyaloshinskii-Moriya interactions in perpendicularly magnetized thin films of Pt/Co/Pt, and show that the insertion of a thin Ir layer leads to reversal of the sign of the effective DMI acting on the sandwiched Co layer, and therefore continuously changes the domain wall structure from the right-to the left-handed Neel wall.

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: This work provides a viable platform for scalable all-electric magnetic logic, paving the way for memory-in-logic applications and demonstrates electrical control of magnetic data and device interconnection in logic circuits.

TL;DR: Direct imaging of Néel domain walls with a fixed chirality in device-ready Pt/Co/AlOx films using Lorentz transmission electron and Kerr microscopies shows that any independently nucleated pair of walls in these films form winding pairs when they meet that are difficult to annihilate with field, confirming that they all possess the same topological winding number.

TL;DR: This work provides a platform to design arrays of correlated nanomagnets and to achieve all-electric control of planar logic gates and memory devices and dominates the behavior of nanomgnets below a critical size.
