Abstract
In this viewpoint article we analyse recent crucial structural, optical and transport experiments onFe3O4 magnetite across theVerwey transition at TV∼120–125 K. We find that all the relevant experimental data are consistent with a model of aPeierls distortion in the cubic spinel lattice, and likewise, some of them evidence againstthe original and still distributed hypothesis of the long range charge orderingorigin of the Verwey transition. An estimated Peierls transition temperature (TP) is comparablewith TV. The Peierls model provides new insight into the electronic properties of magnetite.Application of the Peierls model to some other systems is briefly discussed also.
