磁隧道结中磁液滴的观测
Observation of Magnetic Droplets in Magnetic Tunnel Junctions
摘要：
磁液滴是一类高度非线性的磁动力学孤子，在纳米接触自旋矩纳米振荡器中可以成核和稳定，极大地提高微波输出功率。在这里，我们实验证明磁性隧道结（MTJ）中的磁性液滴。与铁磁共振模式相比，液滴成核伴随着超过300倍的功率增加。液滴的成核和稳定化归因于全垂直MTJ中的双CoFeB自由层结构，其提供了低的Zhang-Li扭矩和高的钉扎场。我们的研究结果使更好的电灵敏度在液滴的基础研究，并表明液滴可以利用在MTJ为基础的应用。
英文摘要：
Magnetic droplets, a class of highly non-linear magnetodynamical solitons, can be nucleated and stabilized in nanocontact spin-torque nano-oscillators where they greatly increase the microwave output power. Here, we experimentally demonstrate magnetic droplets in magnetic tunnel junctions (MTJs). The droplet nucleation is accompanied by a power increase of over 300 times compared to its ferromagnetic resonance modes. The nucleation and stabilization of droplets are ascribed to the double-CoFeB free layer structure in the all-perpendicular MTJ which provides a low Zhang-Li torque and a high pinning field. Our results enable better electrical sensitivity in the fundamental studies of droplets and show that the droplets can be utilized in MTJ-based applications.
