Anisotropic spin-orbit torque generation in epitaxial SrIrO <sub>3</sub> by symmetry design
Bibliographic record
Abstract
Significance Modern spintronics operate based on the spin-to-charge interconversion, where charge current flowing through materials and interfaces with the strong spin-orbit interaction generates spin current via the spin-Hall effect. Here, we report the discovery of a class of intrinsic spin-Hall materials: 5 d transition-metal complex oxides. In these materials, a delicate interplay between spin-orbit coupling and electron correlation exists, which can lead to nontrivial spin-related quantum transport phenomena. In particular, we find that epitaxial perovskite SrIrO 3 thin films generate room-temperature spin currents via the spin-Hall effect more efficiently than those previously reported for elemental heavy metals. Furthermore, the efficiency can be modified by epitaxially tailoring the anisotropic SrIrO 3 crystalline symmetry, thus demonstrating a path toward engineering efficient room-temperature spintronics.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
