A linear/quadratic order parameter coupling description of the Verwey transition in magnetite, Fe3O4

open access: yesActa Crystallographica Section B, Volume 81, Issue 4, Page 427-436, August 2025.
The change in symmetry at the Verwey transition in magnetite puts it in an important class of phase transitions with linear/quadratic coupling between two separate order parameters. We use group theory to characterize the form of the coupling between charge order and an electronic instability, and test the model with structural data.The change in ...
