Abstract

We report on the magnetic properties of MoS 2 measured from room temperature down to 10 K and magnetic fields up to 5 T. We find that single crystals of MoS 2 display ferromagnetism superimposed onto large temperature-dependent diamagnetism and have observed that ferromagnetism persists from 10 K up to room temperature. We attribute the existence of ferromagnetism partly to the presence of zigzag edges in the magnetic ground state at the grain boundaries. Since the magnetic measurements are relatively insensitive to the interlayer coupling, these results are expected to be valid in the single layer limit.
