Electron spin–orbit splitting in a InGaAs/InP quantum well studied by means of the weak-antilocalization and spin-zero effects in tilted magnetic fields
Bibliographic record
Abstract
The coupling between Zeeman spin splitting and Rashba spin–orbit terms has been studied experimentally in a gated InGaAs/InP quantum-well structure by means of simultaneous measurements of the weak antilocalization (WAL) effect and beating in the Shubnikov–de Haas (SdH) oscillations. The strength of the Zeeman splitting was regulated by tilting the magnetic field with the spin-zeros in the SdH oscillations, which are not always present, being enhanced by the tilt. In tilted fields, the spin–orbit and Zeeman splittings are not additive, and a simple expression is given for the energy levels. The Rashba parameter and the electron g -factor were extracted from the position of the spin zeros in tilted fields. A good agreement is obtained for the spin–orbit coupling strength from the spin zeros and WAL measurements.

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.
