论文摘要
混合系统耦合量子自旋缺陷（QSD）和镁可以实现磁性独特的旋转器件功能和探针。在这里，我们通过整合Ferromagnet-Ferroelectric多效性与氮气胶囊（NV）中心旋转，将镁QSD耦合的电场控制添加到此类系统中。将量子弛豫测量与铁磁共振测量和分析建模相结合，我们揭示了观察到的电场调谐是由NV处的镁生成场的铁电偏振控制导致的。利用了所示的控制，我们还提出了具有提高灵敏度的磁化型混合电场传感器。
Hybrid systems coupling quantum spin defects (QSD) and magnons can enable unique spintronic device functionalities and probes for magnetism. Here, we add electric field control of magnon-QSD coupling to such systems by integrating ferromagnet-ferroelectric multiferroic with nitrogen-vacancy (NV) center spins. Combining quantum relaxometry with ferromagnetic resonance measurements and analytical modeling, we reveal that the observed electric-field tuning results from ferroelectric polarization control of the magnon-generated fields at the NV. Exploiting the demonstrated control, we also propose magnon-enhanced hybrid electric field sensors with improved sensitivity.
