  • Recently, significant progress has been made in higher harmonic generation of spin waves in magnetic materials, but it remains challenging to probe the coherence. Here, Lan, Liu et al observe the higher-harmonic spin-wave generation induced by static edge spin textures in a soft ferromagnetic film, and probe the coherence of higher harmonic generation.

  • The perpendicular Néel order in a collinear antiferromagnetic insulator—chromium oxide—can be switched by 180° via the spin–orbit torque with a low current density of 5.8 × 106 A cm−2 and read out via the anomalous Hall effect.

  • Topological semimetal HoPtBi exhibits anomalous AMR effect in paramagnetic state. The AMR exhibits a novel transition from a quasi-twofold to fourfold symmetry and finally forms a stable rotated fourfold symmetry as B increases. C2 and C4 signals with phase angle transitions dominate the novel AMR. Anisotropy of magnetic-field tunable effect induces the topological band change and leads to the phase angle transition.
