Different Orbital Controls on Detrital Magnetic Components in the Ninety‐East Ridge Since the Late Pleistocene

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Magnetic minerals preserved in marginal‐sea sediments can serve as distinct fingerprints for unraveling paleoenvironmental evolution. However, the forcing mechanisms that govern the transport and accumulation of individual magnetic minerals at orbital timescales remain poorly constrained.

Sparse‐Aperture Quasi‐Achromatic Spintronic Terahertz Emitter Enabled by Binary‐Phase Metasurface and Multi‐Spectral Intensity Optimization

Nanophotonics, Volume 15, Issue 19, 13 October 2026.
We propose a sparse‐aperture shared‐aperture design with multispectral intensity optimization, enabling a Pt/W binary‐phase metasurface directly integrated with a spintronic emitter. The device achieves quasi‐achromatic focusing across 1.0–1.5 THz, with intensity fluctuation below 33% and edge preservation above 0.68.

Research on Linear Active Disturbance Rejection Control of Electrically Excited Motor for Vehicle Based on ADP Parameter Optimization

Actuators
In the three-motor hybrid architecture, the auxiliary drive uses electrically excited synchronous motor (EESM), which has the advantages of high torque density, wide speed range and strong anti-demagnetization ability. However, the strong electromagnetic

Asymmetric Spin Canting and Demagnetization Dynamics Driven by Laser Fields in Two-Dimensional Altermagnets

Nano Letters
Laser-induced ultrafast magnetization dynamics have been well established in conventional magnets but remain unexplored in altermagnets (AMs). Using real-time time-dependent density functional theory (rt-TDDFT), we demonstrate that laser pulses can drive asymmetric demagnetization dynamics between the two Fe sublattices in the two-dimensional (2D ...

Magnetic Reconnection Driven by the Impact of a Magnetosheath High‐Speed Jet

Geophysical Research Letters
High‐speed jets (HSJs) are transient structures in the magnetosheath characterized by enhanced dynamic pressure. While recent studies report that HSJs trigger magnetic reconnection at the magnetopause, whether they can directly drive reconnection within ...
