In addition to a storage function through the magnetization of nanowires, domain wall propagation can be used to trigger magnetic logic functions. Here, we present a new way to realize a pure magnetic logic operation by using magnetic nanowires with perpendicular anisotropy. Emphasis is given on the generation of the logic function 'NOT' that is based on the dipolar interaction between two neighbouring magnetic wires, which favours the creation of a domain wall. This concept has been validated on several prototypes and the results fit well with the expectations.
除了通过纳米线的磁化实现存储功能外，畴壁传播还可用于触发磁逻辑功能。在此，我们提出了一种利用具有垂直各向异性的磁性纳米线来实现纯磁逻辑运算的新方法。重点在于基于两根相邻磁线之间的偶极相互作用生成逻辑函数“非”，这种相互作用有利于畴壁的形成。这一概念已在多个原型上得到验证，结果与预期非常吻合。
