Abstract
Magnetic frustration can induce interesting magnetic phases including skyrmion state in centrosymmetric materials. By means of Monte Carlo simulations, we theoretically study the frustrated J
1–J
2 classical Heisenberg model on the triangular lattice. Both h
1–J
2 and h–T phase diagrams show rich magnetic phases, and skyrmion state can be stabilized by J
2. These results can be qualitatively explained by energy competitions, and indicate that skyrmion can be driven by the competition of short-range interactions in absence of DM interaction. This may help us to design and apply the skyrmion devices more easily in the future.
