Observation of a phase transition within the domain walls of ferromagnetic Co3Sn2S2

Changmin Lee et al.

Summary: In this study, researchers discovered a phase transition within the domain walls of Co3Sn2S2, leading to a change in magnetization texture. They propose that this transition is a result of the compound's unique magnetocrystalline anisotropy. This research expands the traditional classification of domain walls and suggests new strategies for manipulating domain walls and their role in electron and spin transport.

Observation of topological Hall torque exerted on a domain wall in the ferromagnetic oxide SrRuO3

Michihiko Yamanouchi et al.

Summary: In a ferromagnetic Weyl metal, a large effective magnetic field exerted on a magnetic domain wall by current has been reported. The ratio of the effective magnetic field to current density shows a nonmonotonic temperature dependence and surpasses the ratios of conventional spin-transfer torques and spin-orbit torques. This enhancement is well described by the topological Hall torque, which is exerted on the domain wall by Weyl electrons emerging around Weyl points under an applied electric field. The ratio of the effective magnetic field arising from the topological Hall torque to current density is over one order of magnitude higher than that originating from spin-transfer torques and spin-orbit torques in metallic systems, indicating that the topological Hall torque may provide a more energy-efficient way to manipulate magnetization in spintronics devices.

Gigantic Current Control of Coercive Field and Magnetic Memory Based on Nanometer-Thin Ferromagnetic van der Waals Fe3GeTe2

Kaixuan Zhang et al.

Summary: The research found that a small current can tune the magnetic state of van der Waals ferromagnet Fe3GeTe2, reducing the coercive field. This is possible because the current generates a highly unusual spin-orbit torque for Fe3GeTe2, and a new model of magnetic memory controlled by a tiny current is demonstrated based on this finding.

Nanoscale domain wall devices with magnetic tunnel junction read and write

E. Raymenants et al.

Summary: In this study, domain wall devices based on perpendicular magnetic tunnel junctions with a hybrid free layer design were developed to achieve electrical read and write, as well as fast domain wall motion driven via spin-orbit torque. The devices showed good performance in terms of tunnelling magnetoresistance readout, spin-transfer torque writing, and domain wall depinning efficiency. Overall, the domain wall conduit based on a synthetic antiferromagnet demonstrated potential for reliable domain wall motion and faster write speed compared to a device based on Pt/Co.
