抄録

We study CP2 skyrmion crystals in the ferromagnetic SU(3) Heisenberg model with a generalization of the Dzyaloshinskii-Moriya interaction and the Zeeman term. The model possesses two different types of skyrmion crystals with unit skyrmions that can be interpreted as bound states of two half-skyrmions or four quarter-skyrmions. Our study on CP2 skyrmion crystals opens up the possibility for useful future applications since CP2 skyrmions have more degrees of freedom than the usual CP1 (magnetic) skyrmions.
