一个微磁模拟进行的装置组成的阵列的方形磁性纳米结构，这是能够不仅是基本的逻辑运算，但也控制信息传输的线性，扇出，交叉的方式通过磁“孤子”。正方形单元表现出形状各向异性，易磁化轴沿着对角线。这使得孤子能够在阵列中的弯曲周围传播，或者在Y形阵列中扇出到两个不同的方向，在特定的外场序列和方向的存在下。最后，在两个阵列的交叉点，独立的孤子交叉也被证明，这完成了设备的逻辑功能。
A micromagnetic simulation is performed of a device consisting of arrays of square magnetic nanostructures, which is capable not only of basic logic operations but also controlled information transfer in linear, fan-out, and crossover manner by means of magnetic “solitons.” The square elements exhibit shape anisotropy, with easy axes along the diagonals. This enables the solitons to propagate around a bend in an array, or to fan-out into two distinct directions in Y-shaped arrays, in the presence of particular external field sequence and direction. Finally, independent soliton crossover at the intersection of two arrays is also demonstrated, which completes the device’s logical functionality.
