The magnetic field around a GaAs/AlGaAs mesa stripe induced by an AC current in the range of 0.3–15.6 μA was observed by magnetic force microscopy (MFM). To confirm the possibility of the vector decomposition of the current-induced magnetic field gradient, we compared the magnetic force signals in the cases of parallel and perpendicular configurations between the MFM cantilever and the current path. In addition, we proposed a novel way of eliminating some effects of electrostatic force, by which a good linearity in the magnetic force signals against the currents was achieved. The spatial resolution of this method was also discussed.
