Robustness of majority gates based on nanomagnet logic

•Evolution of the magnetic state of a majority logic gate made of five nanomagnets.•Observation of asynchronous switching of nominally identical gates.•Slight misalignment of the clocking field can determine wrong operation of the gates.•Strong dipolar coupling between the dots can improve the gate’s performance.•Structural and morphological imperfections of the nanomagnets induce gates errors.
