Abstract

fetched live from OpenAlex

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.

Teacher imitation

Not 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.
