Abstract
Abstract 2D van der Waals magnetic semiconductors have emerged along with the possibilities of achieving an efficient gate tunability and a proximity effect with a high magnetic anisotropy compared with 3D counterparts. Little explored are multiple magnetic phases with a single crystallographic phase. Herein, the multiple magnetic phases in a Mn‐doped SnS 2 single crystal with different doping concentrations using a one‐step self‐flux method are reported. Two ferromagnetic phases with a canted spin direction exist regardless of the Mn‐doping concentration at up to 5 at%. Antiferromagnetism coexists with the ferromagnetic order and strengthens at high Mn‐doping concentrations. A magnetoresistance measurement conducted on a 2 at% Mn‐SnS 2 flake exhibits a positive‐to‐negative crossover with a value of as high as 50% and clear anisotropy, confirming the presence of ferromagnetic order in the material. By revealing multiple magnetic phases in Mn‐doped SnS 2 , the study broadens the scope of state‐of‐the‐art research on layered magnetic semiconductors.
