论文摘要
我们表明，由于传导电子的Bloch振荡，静态电场可引起从铁磁金属到抗铁磁绝缘子的过渡。在稳定状态下，电流与施加的电场成反比，这意味着与Wannier-Stark定位不同的非扰动绝缘性质。讨论了基于最近的Terahertz脉冲源的可能实现实现。
We show that a static electric field induces the transition from a ferromagnetic metal to an antiferromagnetic insulator owing to the Bloch oscillation of conduction electrons. In the steady state, the electric current is inversely proportional to the applied electric field, implying the nonperturbative insulating nature that is different from the Wannier-Stark localization. Possible experimental realization based on recent terahertz pulse sources is discussed.
