Tunable ferromagnetic ordering in phosphorus adsorbed ReS nanosheets.

Layered transition metal dichalcogenides (TMDs) are considered as promising materials for electronic, optoelectronic and spintronic devices due to their outstanding properties. Herein, based on rhenium disulfide (ReS) nanosheets, we realized the intrinsic room temperature ferromagnetism with the adsorption of P adatoms (P-ReS). Experiments indicate that the saturation magnetization (M ) can be tuned by the P ratios, where the maximum M can reach up to 0.0174 emu g. Besides, density functional theory (DFT) calculation results demonstrate that the strong hybridization between Re d and P p orbitals is the main reason of inducing ferromagnetism in P-ReS system. This work provides a novel method to engineer the magnetism of TMDs, endowing them with the possibility of spintronic applications.
