Low power on-chip clocking for nanomagnetic logic circuits
نویسندگان
چکیده
It is demonstrated that it is possible to switch the magnetisation of nanomagnets by employing the exchange interaction between magnets. This can implement on-chip clocking for nanomagnetic logic circuits by using a current-carrying copper wire circularly wrapped by ferromagnetic cladding. This scheme is potentially more energy efficient than yoked cladding clocking using an external magnetic field for magnetisation switching. Maxwell simulation shows that current flowing through copper wire can be reduced by about one hundred times compared with yoked clocking, which means power consumption could be lowered by 10 times. Micromagnetic simulation shows that the nanomagnetic chain aligned on the proposed clocking can achieve a correct functional state.
