Abstract

As one of the transition metal dichalcogenides (TMDs), ReS2 displays several outstanding properties, while the intrinsically nonmagnetic property limits its applications in spin-related devices. In this study, we selected Cr as the dopant to realize the robust room-temperature ferromagnetism in Cr-doped ReS2 (Cr-ReS2) nanosheets. The saturation magnetization (Ms) of the samples can be tuned by changing the Cr concentration. Density functional theory calculation results reveal that Cr dopant can provide the magnetic moments and stable ferromagnetic coupling in Cr-doped ReS2 system. This finding provides an effective approach for designing the new magnetic TMDs in spintronics devices.
