Pressure-Induced Isostructural Antiferromagnetic–Ferromagnetic Transition in an Organic Electride
Bibliographic record
Abstract
Electrides are ionic solids in which cavity-trapped electrons act as anions. These materials have a number of unusual magnetic and electronic properties that originate from the free electrons localized in the crystal voids. Antiferromagnetic (AFM) behavior has previously been observed in organic electride crystals, while it has recently been demonstrated that two-dimensional electrides show strongly anisotropic electrical conductivity and weak itinerant ferromagnetism. In this work, we study the behavior of the simplest organic electride (Cs+(15-crown-5)2e–) under pressure using dispersion-corrected density-functional theory. We predict that this electride undergoes an AFM to FM isostructural transition in the 0.5 to 1.0 GPa range. The electride character of the material is preserved through the transition, which originates exclusively from the spin coupling of the electrons trapped in the crystal voids. The pressure required for the magnetic transition is easily accessible using modern experimental techniques, which opens the door to potential magnetoelectric applications for electride materials.

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
