Abstract

We investigate the influence of the vortex chirality on the magnetization processes of a magnetostatically coupled pair of magnetic disks. The magnetic vortices with opposite chiralities are realized by introducing asymmetry into the disks. The motion of the paired vortices are studied by measuring the magnetoresistance with lock-in resistance bridge technique. The vortex annihilation process is found to depend on the moving directions of the magnetic vorticies. The experimental results are well reproduced by the micromagnetic simulation.
