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 (M s ) 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.
