1. A method of operating a spin torque magnetic device for a logic circuit, the method comprising: inputting current to a majority gate structure of the a spin torque magnetic device, the majority gate structure comprising a free magnetic layer; and, subsequently, outputting a magnetization signal from an output coupled to the majority gate structure, wherein outputting the magnetization signal from the output comprises inputting to another gate structure, and wherein inputting to the other gate structure comprises inputting the magnetization signal without converting the magnetization signal to an electrical signal.
