TLDR
Hall effect measurements were made on a single crystal of magnetite in the temperature range 65 to 373°K as mentioned in this paper, and the Hall voltage was positive over the whole temperature range, which can be explained by assuming that magnetite is a normal semiconductor below the transition point and a degenerate one above that temperature.

Electronic Conduction and Thermopower of Magnetite and Iron‐Aluminate Spinels

TL;DR: In this paper, a small-polaron model of electronic conduction was proposed for magnetite and iron-aluminate spinels at high temperatures, and electrical properties corroborated the previously established cation distribution and defect model.

Two-phase polaron model of conduction in magnetite-like solids

TL;DR: A model and an approximate theory for conduction in solids which have a charge-ordered low-temperature phase and show a first-order phase transition of'semiconductor-semimetal' type at a characteristic temperature Tnu (eg Fe3O4) is presented in this paper.
