反涡创建在一个十字形的导线证明了通过使用磁阻和磁力显微镜测量。磁化过程是随机的，表现出各种各样的磁阻曲线。通过开发一种传统的方法，我们已经实现了电确定标准，以区分从许多其他磁化状态的反涡旋创建。电标准提供了一个简单的方法，没有大规模的设备，并促进进一步的实验，如自旋电流驱动的antivortex动力学。(C)2015日本应用物理学会
Antivortex creation in a cross-shaped wire was demonstrated by using magnetoresistance and magnetic force microscopy measurements. The magnetization process was stochastic and exhibited a wide variety of magnetoresistance curves. By developing a conventional method, we have achieved electrical determination criteria to distinguish antivortex creation from many other magnetization states. The electrical criteria provide a simple method without large-scale apparatus and promote further experiments such as spin-current driven antivortex dynamics.
