  We report a microscopic mechanism for stabilization of biskyrmions in nature
by investigating a minimal classical spin lattice model with nearest neighbour
ferromagnetic Heisenberg exchange and static chiral magnetic interaction on the
triangular lattice. The model is physically motivated model from the Mott
insulators with broken time-reversal symmetry, that is, in the large-$U$ limit
of the one band Hubbard model at half-filling on a two-dimensional lattice in
the presence of external magnetic field. At order $1/U^{2}$, the external
magnetic field can induce a chiral interaction between the three neighbouring
spins. We demonstrate that the chiral magnetic interaction results in
biskyrmion states above a critical value and its strength affects the size of
biskyrmions forming.
