Origin of the Verwey transition in magnetite: Group theory, electronic structure, and lattice dynamics study

Przemyslaw Piekarz, Krzysztof Parlinski, Andrzej M. Oles

The Verwey phase transition in magnetite has been analyzed using the group theory methods. It is found that two order parameters with the symmetries $X_3$ and ${\Delta }_5$ induce the stru…
