Claims

C1strongest claim

with the combination of symmetry analysis and microscopic theory, we explicitly demonstrate the generation of electric polarization by altermagnetic Néel order, and establish a microscopic mechanism of Néel-order-locked electric polarization in altermagnetic multiferroics.

C2weakest assumption

The assumption that the layer group symmetries and the specific altermagnetic Néel order in the chosen monolayer structure are sufficient to produce the polarization without dominant contributions from other interactions or defects (invoked in the symmetry classification and first-principles section of the abstract).

C3one line summary

Altermagnetic Néel order generates locked electric polarization in type-II multiferroics, with a microscopic mechanism, eight symmetry categories for 2D cases, and a first-principles example in monolayer MgFe2N2.
