FIG. 1.

The sketch of a magnetic nanodisk with radius and thickness including a cylindrical cavity with radius and height centered at the negative axis with a distance from the disk center.

FIG. 2.

The vortex structure is excited by magnetic field pulses. The insets are the magnetic states of the disk at different moments. The polarity of VC in the left image is , the second one corresponds to the VC pinned by the cavity, the third one shows the reversal of the polarity of VC, and the right one is . (For interpretation of the references to color in the figure legend, the reader is referred to the online version of this article, where the blue and the red regions in the insets denote the VC with polarity and polarity , respectively.)
