Highly Efficient Room-Temperature Nonvolatile Magnetization Switching in 2D Van Der Waals Ferromagnet Fe<sub>3</sub>GaTe<sub>2</sub>
Bibliographic record
Abstract
The ability to manipulate magnetic states through low currents is crucial for next-generation spintronics. Two-dimensional (2D) magnetic van der Waals (vdW) materials have attracted widespread attention due to their huge spin–orbit torque (SOT) effects. However, the relatively low Curie temperature ( T C ) of most known 2D ferromagnets limits their applications above room temperature. Therefore, the effective manipulation of the magnetic state at room temperature and the integration of multiple storage units remain a challenge. Here, we investigate the fundamental magnetism and nonlocal manipulation phenomena of the room-temperature vdW material Fe 3 GaTe 2 (FGaT) using magneto-optical Kerr effect measurement technology, leading to the successful construction of low-power room-temperature nonvolatile magnetic switches and efficient room-temperature magneto-optical memory devices (MOMD). Notably, the power consumption of the room-temperature magnetization switch and the current density of the MOMD are as low as 5.12 × 10 11 W/m 3 and 5 × 10 4 A/cm 2, respectively. These findings provide solutions for the control and integration of next-generation vdW high-performance spintronic devices.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
