We present experimental evidence of subgigahertz spin-transfer oscillations in metallic nanocontacts that are due to the translational motion of a magnetic vortex. The vortex is shown to execute large-amplitude orbital motion outside the contact region. Good agreement with analytical theory and micromagnetics simulations is found.
我们展示了金属纳米接触中亚吉赫兹自旋转移振荡的实验证据，这种振荡是由磁涡旋的平移运动引起的。结果表明，涡旋在接触区域外执行大幅度的轨道运动。研究发现，实验结果与解析理论和微磁模拟结果吻合良好。
