Using density functional theory calculations and atomistic spin simulations, we propose the existence of room-temperature chiral magnetic textures in ${\mathrm{Fe}}_{2}X\left(X=\mathrm{S},\mathrm{Se},\mathrm{Te}\right)$ monolayers. The intrinsic broken inversion symmetry and strong spin-orbit coupling give rise to an interfacial Dzyaloshinskii-Moriya interaction, which, in conjunction with out-of-plane magnetic anisotropy, enables the stabilization of topological magnetic textures, such as skyrmions and spin spirals, in the absence of an external magnetic field. The chiral spin textures exhibit remarkable thermal stability at room-temperature, significantly enhancing their potential for application in next-generation spintronic devices.
