这些新颖的设备有望凭借其自身的性质改变逻辑运算的范式，取代传统的设备。在这项研究中，我们制作的磁隧道结(MTJ)对两个外部输入(磁场和电压偏置)的响应性质演示了七种基本逻辑操作。这七种操作是通过电场辅助开关特性获得的，其中表面磁电效应是由于足够薄的自由层而产生的。将MTJ转换为一个通用逻辑门，并结合三个辅助电路：多路复用器(MUX)、惠斯通电桥和比较器。有了这些电路，通用逻辑门在一个逻辑级中演示了16次二进制布尔逻辑运算。一种可能的进一步方法是通过多路复用器和比较器的互补来并行计算，能够驱动多个逻辑门。当不同的逻辑运算产生不同的逻辑运算时，也可以实现可重构特性。
The novel devices are expected to shift the paradigm of a logic operation by their own nature, replacing the conventional devices. In this study, the nature of our fabricated magnetic tunnel junction (MTJ) that responds to the two external inputs, magnetic field and voltage bias, demonstrated seven basic logic operations. The seven operations were obtained by the electric-field-assisted switching characteristics, where the surface magnetoelectric effect occurs due to a sufficiently thin free layer. The MTJ was transformed as a universal logic gate combined with three supplementary circuits: A multiplexer (MUX), a Wheatstone bridge, and a comparator. With these circuits, the universal logic gates demonstrated 16 binary Boolean logic operations in one logic stage. A possible further approach is parallel computations through a complimentary of MUX and comparator, capable of driving multiple logic gates. A reconfigurable property can also be realized when different logic operations are produced from different...
