Electric-field-induced formation and annihilation of skyrmions in a two-dimensional magnet

Electric manipulation of skyrmions in two-dimensional (2D) magnetic materials has garnered significant attention due to the potential in energy-efficient spintronic devices. In this work, using first-principles calculations and Monte Carlo simulations, we report the electric-field-tunable magnetic skyrmions in $\mathrm{Mn}{\mathrm{In}}_{2}{\mathrm{Te}}_{4}$ monolayer. By adjusting the magnetic parameters, including the Heisenberg exchange interaction, Dzyaloshinskii-Moriya interaction, and magnetic anisotropy, through applying an electric field, the formation or annihilation of skyrmions can be achieved. Our work suggests a platform for experimental realization of the electric-field-tunable magnetic skyrmions in 2D magnets.
