N2 - The thermal expansion of a synthetic single-crystal sample of magnetite (Fe3O4) in the [111] direction has been investigated for the temperature range of 4.2-300 K using three-terminal capacitance dilatometry. The strain results and corresponding thermal expansion curve show the Verwey transition to be first-order with T-v 120 = 2 K. At T 4.2-70 K, the sample shows Invar-like behaviour.
