As one of promising emerging technologies beyond CMOS

magnetically coupled cellular automata logic device (namely nanomagnet logic device) has the advantages of non-down-lead integration

nonvolatility and ultra low power dissipation.Nanomagnet logic device is comprised of single domain magnets

in which shape of the nanomagnet behaves as an important device characteristic parameter.In this paper

switching behavior of different nanomagnets of peculiar shape is deeply investigated

and the required clocking field to flip the logic states of each nanomagnet of peculiar shape is achieved.According to this finding

a reconfigurable majority logic gate based on nanomagnets of peculiar shape of different sizes is proposed.The OOMMF tool is employed to verify inputs reconfigurability of proposed shape-based gate

and the clocking fields required to sequentially reconfigure different input combinations are obtained.The proposed reconfigurable gate structure lays a solid theoretical foundation for designing programmable magnetic logic computation circuits.
