A method for detecting the helicity of magnetic-moment distribution in vortex states in a ferromagnetic mesoscopic ring has been developed. This method involves measuring an asymmetric component of the resistivity distribution as a function of the external field. This field-induced asymmetry reflects the direction of the magnetic-moment circulation via the anisotropic magnetoresistance effect, which allows precise measurements of magnetic structures.
