TL;DR: In this article, the effects of spin-orbit coupling and inversion asymmetry in a single GdFeCo ferrimagnetic layer, even without a heavy metal interface, were measured using Brillouin light scattering measurement technique.

Measurement of the tilt of a moving domain wall shows precession-free dynamics in compensated ferrimagnets.
TL;DR: It is experimentally demonstrated that magnetic precession vanishes when the net angular momentum is compensated in domain walls driven by spin–orbit torque in a ferrimagnetic GdFeCo/Pt track.
Precession-free domain wall dynamics in compensated ferrimagnets
TL;DR: In this paper, the authors demonstrate that the domain wall precession vanishes with a record mobility when the net angular momentum is compensated (TAC) in DWs driven by spin-orbit torque in a ferrimagnetic GdFeCo/Pt track.

TL;DR: In this paper, the effects of spin-orbit coupling and inversion asymmetry, spinorbit torques (SOTs), Dzyaloshinskii-Moriya interaction (DMI) and chiral magnetism, can co-exist in a single layer ferrimagnetic GdFeCo without any heavy metal interface.

TL;DR: In this article, the effects of spin-orbit coupling and inversion asymmetry exist in a single ferrimagnetic layer, even without a heavy-metal interface, and attribute these effects to a composition variation along the thickness that was observed by scanning transmission electron microscopy.
