The electrical detection of chirality in a magnetic vortex, which is the curling direction of a magnetization structure, is reported. Two electrodes, which were placed on a NiFe microdisc at asymmetric positions with respect to the center of the disc, were used to measure the resistance between them. The magnetoresistance curves with opposite asymmetries due to the anisotropic magnetoresistance effect were observed depending on the chirality of the vortex state, indicating that the asymmetrically placed electrodes are useful for the electrical detection of chirality.
