The Verwey transition refers to a first-order phase transition observed in magnetite (Fe₃O₄), a mixed-valence iron oxide that exhibits a change in its electrical and magnetic properties at a specific temperature, typically around 120 K (−153 °C). At temperatures above the Verwey transition, magnetite behaves as a good conductor, while below this temperature, it becomes an insulator.
