## Abstract The Verwey transition in magnetite is investigated using a band model with interatomic Coulomb energy introduced by Cullen and Callen. This model is treated in the HartreeโFock approximation. A tightโbinding calculation of the band structure with Verwey ordering yields a gap in the sing
By combining ab initio results for the electronic structure and phonon spectrum with the group theory, we establish the origin of the Verwey transition in Fe 3 O 4 . Two primary order parameters with X 3 and 5 symmetries are identified. They induce the phase transformation from the high-temperature
