Query: Spontaneous magnetic skyrmions in single-layer CrInX3(X=Te, Se)   The realization of magnetic skyrmions in nanostructures holds great promise
for both fundamental research and device applications. Despite recent progress,
intrinsic magnetic skyrmions in two-dimensional lattice are still rarely
explored. Here, using first-principles calculations and Monte-Carlo
simulations, we report the identification of spontaneous magnetic skyrmions in
single-layer CrInX3 (X = Te, Se). Due to the joint effect of broken inversion
symmetry and strong spin-orbit coupling, inherent large Dzyaloshinskii-Moriya
interaction occurs in both systems, endowing the intriguing Neel-type skyrmions
in the absence of magnetic field. By further imposing moderate magnetic field,
the skyrmion phase can be obtained and is stable within a wide temperature
range. Particularly for single-layer CrInTe3, the size of skyrmions is sub-10
nm and the skyrmion phase can be maintained at an elevated temperature of 180
K. In addition, the phase diagrams of their topological spin textures under the
variation of magnetic parameters of D, J, and K are mapped out. Our results
greatly enrich the research of 2D skyrmionics physics.
