Abstract
The dependence of the Verwey transition temperature on the nonstoichiometry of has been characterized by thermomagnetic analysis of the initial permeability in magnetite single crystals subjected to subsolidus controlled oxygen fugacity annealing. Nonstoichiometry depresses the transition temperature, which is a maximum for δ=0. For extreme levels of cation deficiency, a second-order transition occurs at 120 K. An anomaly is reported at 250 K.
