摘要:

磁铁矿(Fe $_{3}$ O $_{4}$)的绝缘状态可以被足够大的直流电场破坏。脉冲测量被用来检查这种转变的动力学。开关电压的直方图示出了随着温度降低而变宽的过渡宽度,这与在其他系统中所看到的趋势一致,所述其他系统涉及在存在无序的情况下的“解钉扎”。开关分布也被修改的外部磁场的规模相当于所需的重新取向的磁化。

英文摘要:

The insulating state of magnetite (Fe$_{3}$O$_{4}$) 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 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.
