Room-temperature M - H , ZFC, and FC curves. (a) Room-temperature M-H curves for MoS₂ pristine powders and nanosheets. (b) M-H curves for MoS₂ nanosheets measured at 10 and 300 K: the DM signals of the samples have been deducted. (c) The dependence of the saturation magnetization of the MoS₂ nanosheets on sonication time. (d) The ZFC and FC curves for the exfoliated MoS₂ nanosheets sonicated in DMF for 10 h.
