提出了一种控制奇数边正多边形纳米磁体中涡旋手性的方法。来自均匀磁化状态的涡旋的不对称成核能使我们能够通过面内磁场简单地控制涡旋手征。所提出的方法的可靠性已在三角形，五边形，七边形和九边形坡莫合金纳米磁体的数值和实验证实。作者还证实了当边数为偶数时，涡旋手征是不可控的。c 2010年美国物理学会。[doi：10.1063/1.3521407]
The authors have proposed a control method of the magnetic vortex chirality in regular polygonal nanomagnets with an odd number of sides. The asymmetric nucleation energy of the vortex from the uniformly magnetized state enables us to simply control the vortex chirality by an in-plane magnetic field. The reliability of the proposed method has been numerically and experimentally confirmed in the triangle, pentagonal, heptagonal, and nonagonal Permalloy nanomagnets. The authors also confirmed that the vortex chirality is uncontrollable when the number of the side is even. c 2010 American Institute of Physics. [doi:10.1063/1.3521407]
