利用隧道磁阻结三端器件实现了铁磁圆盘中单涡心开关的真实的实时检测。我们表明，该设备的工作原理作为一个涡旋核心的存储单元，其中阅读和写入可以在一个全电的方式：对应于核心方向的二进制数据可以读出电输出的幅度，而数据可以通过施加脉冲电流写入电。(C)2011年美国物理学会。[doi：10.1063/1.3673303]
A single vortex-core switching in a ferromagnetic disk is detected in real time by using a three-terminal device with the tunneling magnetoresistance junction. We show that the device works as a vortex core memory cell, where reading and writing can be done in an all-electrical way: binary data corresponding to the core direction can be read out electrically as the amplitude of the output, while the data can be written electrically by applying a pulsed current.
