论文摘要
有效地操纵自旋波（SWS）被认为是在下一代Spintronic设备中使用低功耗的信息编码信息的有希望的手段之一。通过操纵SWS繁殖，SW多普勒转移是一种重要现象。在这里，我们预测了通过FM/FE异径中电压控制磁各向异性边界（MAB）运动来控制SW多普勒移动的有效方法。从微磁模拟中，我们验证了SW多普勒在Fe/$ \ rm batio_3 $杂质结构中的理论预测很好地与我们的理论预测一致。 SW多普勒偏移还显示了具有电压的超宽频移（超过5 GHz）的特性。如此有效的SW多普勒移位可能会提供一种测量SW系统中模拟黑洞的鹰辐射的一种可能方法。
Efficient manipulation of spin waves (SWs) is considered as one of the promising means for encoding information with low power consumption in next generation spintronic devices. The SW Doppler shift is one important phenomenon by manipulating SWs propagation. Here, we predict an efficient way to control the SW Doppler shift by voltage control magnetic anisotropy boundary (MAB) movement in FM/FE heterojunction. From the micromagnetic simulation, we verified that the SW Doppler shift aligns well with our theoretical predictions in Fe/$\rm BaTiO_3$ heterostructure. The SW Doppler shift also shows ultra wide-band shift (over 5 GHz) property with voltage. Such efficient SW Doppler shift may provide one possible way to measure the Hawking radiation of an analogue black hole in the SW systems.
