近年来，利用自旋转移纳米振荡器（STNOs）产生微波信号在纳米器件中的应用引起了巨大的和持续的研究兴趣。它们的主要特性是频率可调谐性、纳米尺寸、宽工作温度以及易于与标准硅技术集成。在这篇专题文章中，我们会概述STNO在材料、几何设计和特性方面的最新发展和突破。我们更深入地关注我们在垂直各向异性STNO方面的最新进展，展示了将STNO的输出功率提高到μW范围的方法。还简要讨论了可能成为未来研究的富有成效的主题的STNO的挑战和前景。
The use of spin transfer nano-oscillators (STNOs) to generate microwave signals in nanoscale devices has aroused tremendous and continuous research interest in recent years. Their key features are frequency tunability, nanoscale size, broad working temperature, and easy integration with standard silicon technology. In this feature article, we give an overview of recent developments and breakthroughs in the materials, geometry design and properties of STNOs. We focus in more depth on our latest advances in STNOs with perpendicular anisotropy, showing a way to improve the output power of STNO towards the μW range. Challenges and perspectives of the STNOs that might be productive topics for future research are also briefly discussed.
