Defect-Induced Magnetic Skyrmion in a Two-Dimensional Chromium Triiodide Monolayer

Chromium iodide monolayers, which have different magnetic properties in comparison to the bulk chromium iodide, been shown form skyrmionic states applied electromagnetic fields or Janus-layer devices. In this work, we demonstrate that spin-canted solutions can be induced into monolayer by select substitution of atoms with isovalent impurities. Several concentrations and spatial configurations halide substitutional defects are selected probe coupling between local defect-induced geometric distortions orientation moments. This work provides atomic-level insight how atomically precise chemical doping used create control complex patterns layers lays out foundation for investigating field- geometric-dependent similar two-dimensional materials.
