纳米级磁性逻辑器件是一种新兴的场耦合计算范例，可用于实现非易失性和极低功耗的磁性逻辑电路。然而，杂散磁场和温度波动热效应阻碍了器件和电路的可靠转换。该文研究了对称缺失等腰三角形特殊形状纳磁体的转换特性，提出了利用这种特殊形状纳磁体实现磁性逻辑器件可靠转换的方法。基于特殊形状纳磁体器件设计了流水线RS触发器时序电路，并采用OOMMF软件进行了性能模拟。结果表明，特殊形状纳磁体实现的基本触发器电路不但能够进行可靠的流水线计算，同时还具有较高的工作温度和良好的按比例缩小特征。

Nanoscale magnetic logic device is an emerging field-coupled computing paradigm ,which can be used to realize nonvolatile and ultra low power magnetic logic circuits .However ,stray fields and temperature fluctuation-induced thermal effects sometimes make device and circuit’s switching unreliable .In this paper ,switching behavior of nanomagnet with symmetrically miss-ing isoceles triangle areas is in detail investigated ;an approach of implementing reliable circuit switching by particular nanomagnet shape is proposed .Pipelined RS flip-flop circuit is designed with nanomagnet of particular shape ;OOMMF is employed to simulate the circuit .The results show that the flip-flop constructed with nanomagnet of particular shape can not only perform reliable pipelin-ing computing ,but also demonstrate efficient device scaling and operability at high temperature .
