Spin-based computing schemes could enable new functionalities beyond those of charge-based approaches^,,,,,. Examples include nanomagnetic logic, where information can be processed using dipole coupled nanomagnets^,,,,,,,, as demonstrated by multi-bit computing gates^,. One fundamental benefit of using magnets is the possibility of a significant reduction in the energy per bit compared with conventional transistors^,,,. However, so far, practical implementations of nanomagnetic logic have been limited by the necessity to apply a magnetic field for clocking^,. Although the energy associated with magnetic switching itself could be very small, the energy necessary to generate the magnetic field renders the overall logic scheme uncompetitive when compared with complementary metal–oxide–semiconductor (CMOS) counterparts. Here, we demonstrate a nanomagnetic logic scheme at room temperature where the …
