Abstract
The insulating state of magnetite (Fe3O4) can be disrupted by a
sufficiently large dc electric field. Pulsed measurements are used to examine the
kinetics of this transition. Histograms of the switching voltage show a transition
width that broadens as the temperature is decreased, consistent with trends
seen in other systems involving “unpinning” in the presence of disorder. The
switching distributions are also modified by an external magnetic field on a scale
comparable to that required to reorient the magnetization.
