  Magnetic skyrmions in two-dimensional lattice are a prominent topic of
condensed matter physics and material science. Current research efforts in this
field are exclusively constrained to Neel-type and antiskyrmion, while
Bloch-type magnetic skyrmions are rarely explored. Here, we report the
discovery of Bloch-type magnetic skyrmions in two-dimensional lattice of
MnInP2Te6, using firstprinciples calculations and Monte-Carlo simulations.
Arising from the joint effect of broken inversion symmetry and strong
spin-orbit coupling, monolayer MnInP2Te6 presents large Dzyaloshinskii-Moriya
interaction. This, along with ferromagnetic exchange interaction and
out-ofplane magnetic anisotropy, gives rise to skyrmion physics in monolayer
MnInP2Te6, without needing magnetic field. Remarkably, different from all
previous works on two-dimensional lattice,the resultant magnetic skyrmions
feature Bloch-type, which is protected by D3 symmetry.Furthermore, the
Bloch-type magnetic bimerons are also identified in monolayer MnTlP2Te6. The
phase diagrams of these Bloch-type topological magnetisms under magnetic field,
temperature and strain are mapped out. Our results greatly enrich the research
on magnetic skyrmions in twodimensional lattice.
