Abstract

fetched live from OpenAlex

Abstract Quantum phenomena such as superconductivity usually emerge in strongly correlated oxide systems as the result of the interplay of spin, charge, and orbital degrees of freedom. Adding ferromagnetism to two‐dimensional electron gases (2DEGs) at oxide interfaces is intriguing due to their scientifically exotic and technically valuable properties, which may lead to new fundamental understanding and multifunctional applications. Here, ferromagnetic 2DEGs at the interface of polar antiferromagnetic LaTiO 3 and nonpolar antiferromagnetic EuTiO 3 are generated. The magnetotransport properties of these 2DEGs depend on the thickness of LaTiO 3 that determines the carrier concentration, with all showing robust ferromagnetism up to 5.5 K. This magnetism is intrinsic to the strongly‐correlated 2D electron system and is highly sensitive and tunable based on the sample configuration. Thus, a prototype oxide system with magnetic functionality for spintronics and ferromagnetic semiconductors has been developed.

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.
