Abstract

We have proposed a method for controlling the vortex chirality in a regular polygonal nanomagnet with an odd number of sides using an in-plane magnetic field. We confirmed the reliability of the proposed method in the triangle, pentagonal and heptagonal nanomagnets by using micromagnetic simulation. However, when the number of the sides is 9 or more, the chirality does not change systematically because of the insufficient in-plane shape anisotropy. Stabilizations of a single vortex in polygonal nanomagnets with an even number of sides have been also investigated.
