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 missing 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 pipelining computing
but also demonstrate efficient device scaling and operability at high temperature.
