TL;DR: Non-zero topological charge prevents the straight motion of ferromagnetic skyrmions and hinders their applications, so ferrimagnetic GdFeCo films can move with high velocity and reducedSkyrmion Hall angle.

TL;DR: In this article, the accumulation and dissipation of magnetic skyrmions in ferrimagnetic multilayers can be controlled with electrical pulses to represent the variations in the synaptic weights.

TL;DR: The authors' measurements reveal how the magnetic symmetry is broken by the concerted action of the damping-like and field-like spin-orbit torques and the Dzyaloshinskii-Moriya interaction, and show that reproducible switching events can be obtained for over 1012 reversal cycles.

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: In this article, an electrically-operating skyrmion-based artificial synaptic device designed for neuromorphic computing was presented, where current-induced creation, motion, detection and deletion of skyrms in ferrimagnetic multilayers can be harnessed in a single device at room temperature to imitate the behaviors of biological synapses.
