我们利用磁光克尔效应测量了直径为3 μm的单个图案化反铁磁耦合超晶格元件中棘齿孤子的传输。研究了体开关场和孤子传输场随单元尺寸的变化。结果发现，在本文研究的长度尺度上，我们没有看到棘轮行为随单元尺寸的变化而显着变化。讨论了孤子传输的裕度和与缩小尺度相关的附加特征。
We demonstrate ratchet soliton propagation in individual patterned antiferromagnetically coupled superlattice elements down to 3 μm diameter using magneto-optical Kerr effect measurements. The bulk switching and soliton propagation fields are investigated as a function of the element size. It is found that on the length scale investigated here we do not see significant variation in ratchet behavior depending on the element size. The margin for soliton propagation and additional features related to downscaling are discussed.
