Inhomogeneous magnetoelectric structures
Bibliographic record
Abstract
Many studies have been devoted to the magnetoelectric (ME) effect in connection with its possible use in the creation of new promising electronic devices. Special attention is paid to the analysis of the ME structure, which mainly determines the properties of a new ME device. At the same time, in practice, experimental studies of inhomogeneous ME structures often prevail and the theoretical calculation of which, as a rule, is quite complex. The authors consider the calculation of inhomogeneous ME structures in the longitudinal and bending modes in this paper. It is of practical interest to take into account the inhomogeneities associated with the location of the electrodes and the different lengths of the piezoelectric and magnetostrictive components of the ME structure. The results obtained showed that the excess of the magnetic component length determines the value of the converse ME coefficient, and in the case of using a symmetric structure to create low-frequency ME antennas, the optimal value of the excess parameter is 1.4–2.5. In the opposite case, reducing the length of the magnetic component by 25% in order to connect the electrodes to the asymmetric structure leads to a significant decrease in the ME voltage coefficient to 50%. At the same time, the use of variable-size electrodes for an asymmetric structure in the bending mode indicates the possibility of a significant increase in the ME voltage coefficient. A comparison of theoretical and experimental results is carried out.

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.
