High-field magnetoresistance effects and temperature-dependent spin relaxation in rubrene nanowire spin valves
Bibliographic record
Abstract
In this work we discuss the high-field magnetoresistance effects and temperature-dependent spin relaxation in rubrene nanowire spin valves. Rubrene thin film spin valves have been studied by several groups in the past since this material can potentially offer long spin relaxation length (Ls). However, the Lsvalues reported so far have been low, typically ∼10 nm at low temperatures (∼10K). Recently we have reported a vertical spin valve device using rubrene spacer, in which rubrene is patterned in a nanowire array geometry. Such patterning leads to significant suppression of spin relaxation and we have reported spin relaxation length of ∼47 nm at ∼10K in rubrene nanowires. In this work we present the high field magnetoresistance measurements performed on rubrene nanowires and discuss the possible origins of these effects. Further, we discuss possible origin of the observed temperature-dependence of spin relaxation length.

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.
