Spectroscopic and magnetic properties of colloidal transition metal-doped transparent conducting oxide nanocrystals as building blocks for spintronic materials
Bibliographic record
Abstract
The synthesis of colloidal Cr3+-doped In2O3 NCs with the body-centered cubic bixbyte-type crystal structure, and Cr3+-doped SnO2 NCs with the rutile crystal structure was described. Ligand-field electronic absorption spectroscopy suggests that Cr3+ dopants have quasi-octahedral coordination in both In2O3 and SnO2 NC host lattices. Unlike free-standing nanocrystals, the nanocrystalline films fabricated from colloidal Cr3+-doped In2O3 and SnO2 nanocrystals exhibit room temperature ferromagnetism. Analogous magnetic behavior suggests the same origin of ferromagnetic ordering in both materials. The observed ferromagnetism has been related to the existence of extended structural defects, formed at the interfaces between nanocrystals in nanocrystalline films. These structural defects are likely responsible for the formation of charge carriers which mediate the dopant magnetic moment ordering.

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.
