Abstract
We study the effect of magnetic anisotropy on the field-driven evolution of magnetic structure in a nanodisk with existence of Dzyaloshinskii-Moriya interaction by using micromagnetic simulations. We obtain the phase diagram of magnetic state in the magnetic field-magnetic anisotropy constant (Hz-K) plane. It is found that target skyrmion can stably exist at zero external magnetic field when the magnetic anisotropy constant changing in a large range. The evolution of magnetic state with the perpendicular magnetic field strongly depends on the magnetic anisotropy constant.
