    • Abstract

       

      The origin of Verwey transition in magnetite is investigated. It is shown that the transport properties in the high temperature phase of magnetite can be accounted by a phonon-induced correlated electron transfer mechanism. Assuming that the condensation of this phonon mode leads to Verwey transition, the isotope and pressure effects have been explained. The electron energy band diagram consistent with the electrical transport behaviour in the low temperature phase has been constructed.
