Controlling the Magnetic Properties of the van der Waals Multiferroic Crystals Co${}_{1-x}$Ni${}_x$I${}_2$

Anastasiia Lukovkina, Sara A. Lopez-Paz, Celine Besnard +3

The structurally related compounds NiI${}_2$ and CoI${}_2$ are multiferroic van der Waals materials, in which helimagnetic orders exist simultaneously with electric polarization. Here,…
