"magnetism-related property of electrons points up or down and can be read, like electric charge can, as 1 or 0... applying positive voltage, spins of underlying chromium oxide point up, ultimately forcing spin orientation of graphene’s electric current to veer left and yield a detectable signal. Negative voltage instead flips the spins of the chromium oxide down, with the spin orientation of the graphene’s current flipping to the right and generating a signal clearly distinguishable from the other"
