论文摘要
通过磁绝缘子的自旋传输已在多种材料中证明，是下一代基于自旋计算的新兴途径。为了调节这些系统中的自旋传输，通常会应用一个足够强的磁场以确定对磁性的控制。在这里，我们利用众所周知的多磁电磁电气BifeO3，在没有施加磁场的情况下证明了热激发木片电流的非挥发性，滞后，电场控制。这些发现是迈向基于磁通的设备的重要一步，在这种设备中，仅电场控制是非常需要的。
Spin transport through magnetic insulators has been demonstrated in a variety of materials and is an emerging pathway for next-generation spin-based computing. To modulate spin transport in these systems, one typically applies a sufficiently strong magnetic field to allow for deterministic control of magnetic order. Here, we make use of the well-known multiferroic magnetoelectric, BiFeO3, to demonstrate non-volatile, hysteretic, electric-field control of thermally excited magnon current in the absence of an applied magnetic field. These findings are an important step toward magnon-based devices, where electric-field-only control is highly desirable.
