FIG. 1.

(a) Formation of the magnetic vortices with mutually opposite chiralities by introducing the positive vertical magnetic field . After the application of the magnetic field, the chiralities of disk and disk are CW and CCW, respectively. (b) Inward vortex motion by applying a positive horizontal magnetic field . (c) Outward vortex motion by applying a negative horizontal magnetic field.

FIG. 2.

(a) Schematic diagram of the bridge circuit for the magnetoresistance measurement together with a SEM image of the fabricated paired asymmetric disks. (b) Resistance of disk as a function of the vertical magnetic field together with the corresponding domain structures calculated by micromagnetic simulations. (c) Resistance of disk as a function of the vertical magnetic field together with the corresponding magnetic structures. After the nucleation of the vortex, the magnetic field is swept from 0 back to .

FIG. 3.

(a) Resistance of disk as a function of the positive horizontal magnetic field. The vortices approach with increasing magnetic field. (b) Resistance of disk as a function of the negative horizontal magnetic field. the vortex cores separate with increasing negative magnetic field. The arrows indicate the vortex annihilations.
