NiI2 is a layered 2D magnetic materials with exotic magnetic properties. The crystal structure consists of weakly coupled NiI2 individual sheets interacting through weak van der Waals forces. Recent studies have shown that 2D NiI2 sheets are promising 2D intrinsic FM semiconductors. Their exfoliation energy is smaller than that of graphene or MoS2 meaning it is easily to yield monolayers using exfoliation or polymer assisted techniques. Like other Ni based dihalides NiI2 monolayers show semiconducting band gap (theoretical) at around 1.25eV much similar to Si and GaAs range. The FM transition temperature of NiI2 has been predicted one of the highest at Tc~170K in the monolayer form. NiI2 crystals have been synthesized using high purity precursors to attain 6N pure vdW crystals with perfect exfoliation characteristics using self flux zone growth technique. Easy exfoliation characteristics and large single domain sizes make it easier to yield monolayer and few-layer sheets onto other substrates using standard mechanical or polymer assisted exfoliation techniques.
