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.
