Magnetic Nanosheets via Chemical Exfoliation of K2x Mn x Sn1–x S2

We report two chemical routes to prepare new magnetically doped two-dimensional (2D) tin sulfides, i.e., Mn x Sn1–x S2 (x = 0.1–0.2), as derivatives of K2x Mn x Sn1–x S2. Initial codoping with K ensures high Mn doping in the nanosheets and is additionally aiding exfoliation. In chemical route 1, the parent compound is first reacted with a diluted HCl solution, which dissolves all K and half the Mn atoms, followed by treatment with …
