Synthesis and lithographic applications of highly metallized cluster‐based polyferrocenylsilanes
Bibliographic record
Abstract
Abstract We report the use of a cobalt‐clusterized polyferrocenylsilane (Co‐PFS) as a precursor to patterned ferromagnetic ceramics. Co‐PFS was synthesized. Functioning as a negative resist, Co‐PFS lines with widths of 10‐300 μm were patterned using UV‐photolithography, while features as small as 500 nm were afforded by electron‐beam lithography. Subsequent pyrolytic treatment of the lithographically patterned Co‐PFS yielded ferromagnetic ceramics containing Fe/Co nanoparticles. Due to its high metal‐loading, Co‐PFS is a good etch resist for oxygen and hydrogen plasma reactive ion etching. Reactive ion etching of a thin film of Co‐PFS in a secondary magnetic field allowed direct access to ferromagnetic ceramic films, providing a viable alternative to pyrolysis.

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.
