The disclosed technology generally relates to magnetic devices and more particularly to spin torque majority gate devices, and to methods of operating such devices. In one aspect, a majority gate device comprises a free ferromagnetic layer comprising 3N input zones and an output zone. The output zone has a polygon shape having 3N sides, where each input zone adjoins the output zone. The input zones are arranged around the output zone according to a 3N-fold rotational symmetry, where N is a positive integer greater than 0. The input zones are spaced apart from one another by the output zone. The majority gate device additionally comprises a plurality of input controls, where each of the input zones is magnetically coupled to a corresponding one of the plurality of input controls, where each of the input controls is configured to control the magnetization state of the corresponding input zone. The majority gate device further comprises an output sensor magnetically coupled to the output zone, where the output sensor is adapted for sensing the magnetization state of the output zone. Each input zones adjoins the output zone at one of the 3N sides.
