Abstract

fetched live from OpenAlex

We describe our cryogenic magnetic force microscope, operating between 4.2 and 300 K, in fields of 0–8 T. The system uses a fiber optic interferometer to measure cantilever deflections, permitting the tracking of the resonance frequency through the use of a phase locked loop. Piezoelectric positioners, capable of operation in high magnetic fields, perform in situ tip and fiber approaches. As an effective means of vibration isolation, we suspend the microscope from a soft bellows which attenuates vibrations by more than an order of magnitude. A detailed noise analysis indicates that although the microscope is thermally limited, the system frequency resolution is currently limited by the shot noise of the interferometer.

Full frame distilled prediction

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.
