Tunable ferromagnetic ordering in phosphorus adsorbed ReS 2 nanosheets

Abstract 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 2 ) nanosheets, we realized the intrinsic room temperature ferromagnetism with the adsorption of P adatoms (P-ReS 2 ). Experiments indicate that the saturation magnetization ( M s ) can be tuned by the P ratios, where the maximum M s can reach up to 0.0174 emu g −1 . 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 2 system. This work provides a novel method to engineer the magnetism of TMDs, endowing them with the possibility of spintronic applications.
