Ferromagnetic Properties of Ni9S8/MoS2 Hybrid Structure

Two-dimensional transition metal dichalcogenides have made a tremendous progress during last two decades owing to their use in technologically important applications like electronics, optoelectronics, magnetism, and energy storage applications. Herein, we present synthesis of nanosheets of Ni9S8/MoS2 hybrid nanosheet using the hydrothermal method and induction of ferromagnetism is being reported at room temperature as well. Magnetic properties of both pristine MoS2 and hybrid Ni9S8/MoS2 were probed using experimental techniques; it is revealed that unlike pristine MoS2, hybrid Ni9S8/MoS2 shows ferromagnetic behavior both at room temperature and at low temperature (5 K). It is proposed that ferromagnetism in this hybrid structure is being caused by the introduction of Ni atoms.
