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.
